Because of the thermodynamic demands of N2 cleavage, N2-derived nitride complexes are often unreactive. The development of multistep N2 functionalization reactions hinges on methods for modulating nitride reactivity with supporting ligands. Here, we describe the reactions of N2-derived Re-nitride complexes, including the first Re nitrides supported by a nitroxide-containing pincer ligand, and unusual examples of Re6+-nitride complexes. The previously reported N2-derived complex (PNP)Re(N)(Cl) (PNP = N(CH2CH2PtBu2)2) can be oxidized by O atom transfer to the backbone amide to form a novel nitroxide-pincer complex or by 1e- to form a rare S = 1/2 Re6+-nitride complex. The Re-nitrido interaction in a series of Re- and ligand-oxidized complexes is characterized using 15N NMR spectroscopy, IR spectroscopy, and DFT calculations, and shows changes in the Re-N bond order from both ligand- and metal-centered oxidations. Chemical oxidation of the supporting ligand to form a nitroxide-pincer ligand results in subtle electronic changes at Re and a more electron-deficient nitride ligand. Combined ligand- and metal-centered oxidation to form a Re6+-nitroxide complex results in a reversal of reactivity at the nitride ligand from nucleophilic to electrophilic. These systematic electronic structure and reactivity studies demonstrate methods for inducing reactivity in N2-derived nitride complexes.

A series of ruthenium hydride N-alkyl heterocyclic carbene complexes has been investigated as catalysts for a tandem oxidation/Wittig/reduction reaction to give C-C bonds from alcohols. The C-H-activated carbene complex Ru(I iPr2Me2)?(PPh3) 2(CO)H (9) proves to be the most active precursor catalyzing the reaction of PhCH2OH and Ph3P=CHCN in 3 h at 70 C. These results provide (a) a rare case in which N-alkyl carbenes afford higher catalytic activity than their N-aryl counterparts and (b) a novel example of the importance of NHC C-H activation in a catalytic cycle.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1038-95-5 is helpful to your research., Electric Literature of 1038-95-5

Silver(I) derivatives containing tertiary phosphines and anionic tetrakis(pyrazol-1-yl)borates were prepared from AgO3SCF3, PR3 (R = phenyl, benzyl, cyclohexyl, 2,4,6-Me3C6H2, o-, m- or p-tolyl) or PPh2R? (R? = methyl or ethyl) and K[B(pz)4] or K[B(mpz)4] (Hpz = pyrazole, Hmpz = 3-methylpyrazole) and characterized through analytical and spectral (IR, 1H, 13C and 31P NMR) measurements. These compounds are stable, soluble in chlorinated solvents, and non-electrolytes in CH2Cl2 and acetone. Room-temperature single-crystal structural characterizations were made for several of them. The pyrazolyl ligand is potentially maximally tridentate, and the maximally four-co-ordinate array about the silver potentially of threefold symmetry (excepting the fourth pz moiety) where the symmetry of the phosphine permits. The variation in the silver(I) co-ordination number and environment in various combinations of various degrees of steric interaction among the above entities has been explored. The reactivity of [{AgB(pz)4} {P(C6H4Me-m)3}] and [{AgB(pz)4} {P(C6H4Me-o)3}] towards unidentate N-, S- and P-donors was also investigated.

Triphenylphosphonium (TPP+) species comprising multiple charges, i.e., bis-TPP+, are predicted to be superior mitochondrial-targeting vectors and are expected to have mitochondrial accumulations 1000-fold greater than TPP+, the current “gold standard”. However, bis-TPP+ vectors linked by short hydrocarbon chains (n < 5) are unable to be taken up by the mitochondria, thus hindering their development as mitochondrial delivery vectors. Through the incorporation of methylated TPP+ moieties (T*PP+), we successfully enabled the accumulation of bis-TPP+ with a short linker chain in isolated mitochondria, as measured by high performance liquid chromatography. These experimental results are further supported by molecular dynamics and ab initio calculations, revealing the strong correlations between mitochondria uptake and molecular volume, surface area, and chemical hardness. Most notably, the molecular volume has been shown to be a strong predictor of accumulation for both mono- and bis-TPP+ salts. Our study underscores the potential of T*PP+ moieties as alternative mitochondrial vectors to overcome low permeation into the mitochondria.

Efficient, phosphine-directed ortho C?H borylation of arylphosphine derivatives was achieved using Ru catalysts for the first time. The reaction is applicable to various tertiary arylphosphine and arylphosphinite derivatives to give (o-borylaryl)phosphorus compounds in high yields. This reaction enables easy access to a variety of functionalized phosphine ligands and ambiphilic phosphine boronate compounds, thus realizing a new late-stage modification of phosphorus compounds.

IR spectra of complexes 1-4 show the characteristic thioureide (C-N) bands at higher wave numbers compared to that of the parent dithiocarbamate complex [Ni(dedtc)2]. The d-d transitions are observed in the region 452-482 nm. The CV studies clearly show the presence of reduced electron density on the nickel ions in mixed ligand complexes 1-4 compared to the parent dithiocarbamate. Single crystal X-ray structure studies show all the complexes to containplanar NiS2P 2, NiS2PN, and NiS2PC chromophores in keeping with the observed diamagnetism. In all the complexes the Ni-S distances are asymmetric. The thioureide C-N distance of the complexes 1-4 are less thanthe C-N distance observed in the parent [Ni(dedtc)2].

In quest of new metallo-pharmaceuticals with enhanced anticancer activity, four new phosphine- and carbodithioate-based Pd(II) complexes of the type [(R)CS2Pd(PR3)Cl] (where R = 4-(2-hydroxyethyl)piperazine (1, 2), dibenzyl (3, 4); PR3 = diphenyl(p-tolyl)phosphine (1, 3), tris(4-tolyl)phosphine (2, 4)) were synthesized and characterized using elemental analysis, Fourier transform infrared and NMR (1H, 13C and 31P) spectroscopies and single-crystal X-ray diffraction. The X-ray diffraction data confirmed the pseudo square-planar geometry ensuring bidentate coordination mode of carbodithioate ligands. Anticancer activity of the synthesized complexes and their ligands was assessed against human lung (A549), breast (MCF-7) and prostate (PC3) carcinoma cells using MTT assay. All the tested compounds showed activity in micromolar range. In many cases, the cytotoxicity of the synthesized complexes was higher than or comparable to that of the standard drugs cisplatin and doxorubicin. Complex 3 emerged as the most promising compound with the lowest IC50 values of 4.83, 3.72 and 5.11 muM for A549, MCF-7 and PC3 carcinoma cell lines, respectively. DNA binding studies were also carried out using UV?visible spectroscopy. We extended our investigations to explore the mechanism of anticancer activity using in silico tools. Based on the mechanism of action of standard drugs used, extensive docking studies were carried out on the three different biomolecular targets.

Diastereomerically pure secondary alcohols epimerize to mixtures of diastereomers in C6H5R at 65-90 C in the presence of 10 mol % (eta5-C5R5)Re(NO)(PPh3)(OCH 3) (1; R = H, Me). The methoxide ligand of 1 first exchanges with the alcohol substrate to give alkoxide complexes (eta5-C5R5)Re(NO)(PPh 3)(OCHR?R?) (2). Authentic samples of diastereomerically and enantiomerically pure 2 are prepared, where OCHR?R? is derived from (+)- and (-)-, exo- and endo-borneol. NMR data show that epimerization occurs first at rhenium (ca. 35 C) and then at carbon (ca. 65 C). Substitution reactions and rate experiments show that PPh3 initially dissociates from 2 with anchimeric assistance by alkoxide oxygen lone pairs. An intermediate with a trigonal-planar rhenium, which can either return to 2 (with epimerization at rhenium) or undergo beta-hydride elimination to a ketone hydride complex (leading to epimerization at carbon), is proposed. Accordingly, rates of epimerization at carbon (but not rhenium) are strongly inhibited by added PPh3, and show a significant kH/kD.

The complex trans-[Rh(NCBPh3)(H)(SnPh3)(PPh3)2] (1) reacts with pyridine and substituted pyridines (L) in dichloromethane at 22 C to give [Rh(NCBPh3)(H)(SnPh3)(PPh3)(L)] (2a) and at -25 C to give trans-[Rh(NCBPh3)(H)(SnPh3)(PPh3)2(L)] (3a). These complexes and numerous analogues can be prepared (the majority in solution only) by the reactions of [Rh(X)(PPh3)3] (X = NCBPh3 (a), N(CN)2 (b), NCS (c), N3 (d), NCO (e), O2CCF3 (f), Cl (g)) with Ph3SnH in solutions containing pyridines (4-Rpy; R = CO2Me, H, NMe2), 1-methylimidazole (1-Meim), and benzonitriles (4-RC6H4CN; R = COMe, H, NMe2) (L). NMR data for the series of complexes 2 in which ligands X, L, and, for X = Cl, the phosphine P(4-C6H4R)3 (R = F, H, Me) were varied independently show systematic changes in the parameters delta(119Sn), delta(103Rh), J(119Sn-1H), and J(103Rh119Sn), which are related to the electron-donating properties of X, L, and the phosphine. Plots of J(119Sn-1H) against delta(119Sn), delta(103Rh), and J(103Rh-119Sn) are approximately linear and show delta(103Rh) and J(103Rh-119Sn) increasing with J(119Sn-1H) and delta(119Sn) decreasing. Complexes 3 give higher values of J(119Sn-1H) and lower values of delta(119Sn) than found for the less electron-rich 2, with data for 3 continuing the trends in J(119Sn-1H) and delta(119Sn) observed for 2. Values of delta(103Rh) and J(103Rh-119Sn) for 3 do not match the pattern found for 2; nor do data for an isomeric form of 3, cis-[Rh(Cl)(H)(SnPh3)(PR3)2(L)] (L = benzonitriles) (4). The plot of J(119Sn-1H)/delta(119Sn) for 3 shows discontinuities at high values of J(119Sn-1H), with the trend in delta(119Sn) toward more negative values (as the ligands become more nucleophilic) being transformed into an increase and changes in J(119Sn-1H) becoming smaller. These patterns of NMR data are interpreted in terms of the weakening of an Rh-(H-Sn) three-center interaction and changes in the coordination geometry of tin as the electron density on rhodium is increased.
