One-Pot Halogen Dance/Negishi Coupling of Dibromothiophenes for Regiocontrolled Synthesis of Multiply Arylated Thiophenes

One-pot halogen dance/Negishi cross-coupling of readily available 2,5-dibromothiophenes is described. A lithium diisopropylamide (LDA)-mediated halogen dance reaction resulted in the formation of thermodynamically stable alpha-lithiodibromothiophenes, which were transmetalated with ZnCl2and subjected to Negishi cross-coupling to provide the corresponding arylated dibromothiophenes in one pot. The resultant beta-bromo group was much less reactive than the remaining alpha-bromo group, which was used in a one-pot double Suzuki?Miyaura cross-coupling, enabling facile synthesis of multiply arylated thiophenes.

Synthesis, Characterization, DNA Interaction Study, Antibacterial and Anticancer Activities of New Palladium(II) Phosphine Complexes

A series of palladium(II) complexes with N,N-dimethylthiourea and phosphines [tri-p-tolylphosphine (Tptp), benzyl(diphenyl)phosphine (Bdp), cyclohexyl(diphenyl)phosphine (Cdp)] were synthesized by the direct reaction of K2[(PdCl4)] with the corresponding phosphines and then with N,N-dimethylthiourea at a molar ratio of 1: 2: 2. The general formula of these complexes is [Pd(L1)2(L2)2]Cl2, where L1 = N,N-dimethylthiourea (Dmtu), L2 = Tptp, Bdp, Cdp. The complexes were characterized by elemental analyses, multinuclear NMR (1H, 13C, 31P), and FT-IR. The complex with cyclohexyl(diphenyl)phosphine was also characterized by single crystal X-ray analysis. The spectral and crystallographic data suggest monodentate coordination of dimethylthiourea through the sulfur atom and of the phosphine ligand through the phosphorus atom and distorted square planar environment of palladium(II). The synthesized complexes have been screened for DNAbinding, antibacterial, cytotoxic, and antitumor activities. The complexes show interaction with DNA via intercalative mode. The complexes show good activity against both gram positive and gram negative bacteria as compared to that of a standard drug, Imipenem. Their antitumor activity against MCF7 tumor cell line was found to be comparable with doxorubicin. MTT assay was used to investigate the cytotoxicity of the studied compounds having activity order: 3 > 2 > 1.

[Pd(acac)(L)2][BF4] (L?=?morpholine, diethylamine, dibutylamine, dioctylamine): Synthesis, structure and their catalytic activity

Cationic acetylacetonate bis(secondary amine) palladium (II) complexes were synthesized by nitrile substitution of [Pd(acac)(MeCN)2][BF4] with L (L?=?morpholine, diethylamine, dibutylamine, dioctylamine) which yielded [Pd(acac)(L)2][BF4] as a mononuclear species with chelating acac ligand. An X-ray diffraction, NMR, IR and DFT study of [Pd(acac){morpholine}2][BF4] establishes the presence of hydrogen bonding between the morpholine ligand and [BF4]? anion. Crystallographic defects in the crystal and presence of pseudocrystalline structure in solution of [Pd(acac){morpholine}2][BF4] were assumed to explain IR spectra features. Preliminary investigations into the polymerization of norbornene, dimerization of styrene, and telomerization of 1,3-butadiene with diethylamine were performed.

A highly efficient and practical method for catalytic Asymmetric Vinylogous Mannich (AVM) reactions

(Chemical Equation Presented) Very selective but very easy: These are two of the attributes of the asymmetric vinylogous Mannich reactions presented herein. These reactions can be run on a gram scale and in undistilled THF and air (see scheme; TMS = SiMe3). All that is needed is commercially available AgOAc, a readily available amino acid derived phosphine, and a commercially available or easily prepared (one step) siloxyfuran.

Human Serum Albumin-Delivered [Au(PEt3)]+ Is a Potent Inhibitor of T Cell Proliferation

Using a modular library format in conjunction with cell viability (MTS) and flow cytometry assays, 90 cationic complexes [AuPL]n+ (P = phosphine ligand; L = thiourea derivative or chloride) were studied for their antiproliferative activity in CD8+ T lymphocyte cells. The activity of the compounds correlates with the steric bulk of the phosphine ligands. Thiourea serves as a leaving group that is readily replaced by cysteine thiol (NMR, ESI-MS). Taking advantage of selective thiourea ligand exchange, the fragments [Au(PEt3)]+ and [Au(JohnPhos)]+ (JohnPhos = 1,1?-biphenyl-2-yl)di-tert-butylphosphine) in compounds 1 and 2 were transferred to recombinant human serum albumin (rHSA). PEt3 promoted efficient modification of Cys34 in HSA (HSA-1), whereas use of bulky JohnPhos as a carrier ligand led to serum protein nonspecifically modified with multiple gold adducts (HSA-2) (Ellman?s test, ESI-TOF MS). HSA-1, but not HSA-2, strongly inhibits T cell proliferation at nanomolar doses. The potential role of HSA as a delivery vehicle in gold-based autoimmune disease treatment is discussed.

Synthesis and structural characterization of palladacycles with polydentate ligands by a stepwise coupling route – Palladacycles containing halides as efficient catalysts and substrates

A series of ferrocenyl palladacycles with polydentate ligands were conveniently prepared by the Suzuki coupling reactions of a halide-containing ferrocenyl palladacycle [PdCl({(nu5-C5H 5)}Fe{(nu5-C5H3)N 2C4H2Cl})(PPh3)] (1) andarylboronic acids without additional palladium catalysis. In the absence of additional base, amination also occurred in high yield. This new protocol was successfully applied to the Suzuki coupling reactions of the analogous halide-containing palladacycle [PdCl({(nu5-C5H5)} Fe{(nu5-C5H3)NC5H 3Br})(PPh3)] (15) and Buchwald-Hartwig amination of the analogous complex [PdCl({(nu5-C5H5)} Fe{(nu5-C5H3)NC5H 3Br})(DCPAB)] (32), where DCPAB = 2-dicyclohexylphosphanyl-2?- (N,N-dimethylamino)biphenyl. The halide-containing palladacycles act as efficient catalysts and substrates in the coupling reactions. 37 new examples have been fully characterized by elemental analysis, IR and 1H NMR spectroscopy, and ESI-MS. Additionally, the molecular structures of eight compounds were determined by single-crystal X-ray diffraction, and many types of intermolecular C-H¡¤¡¤¡¤Cl (O, N, pi) interactions and pi-pi interactions were found in the crystal structures of these palladacycles. An efficient method for the synthesis of palladacycles with polydentate ligands by a stepwise coupling route without additional catalysis is presented. The halide-containing palladacycles act as efficient catalysts and substrates in coupling reactions. 37 examples and the crystal structures of eight samples are reported.

Synthesis by direct arylation of thiazole-derivatives: Regioisomer configurations-optical properties relationship investigation

The synthesis of thiazole(Tz)-based regioisomer materials using selective direct arylation to avoid any protection steps has been developed. A series of trimers in which the Tz groups sandwich either an electron-rich or an electron-deficient unit, with a regioselective orientation of the respective Tz unit, has therefore been synthesized. This chemical strategy has also been followed to synthesize a second series of pentamers in which the Tz group is used as a conjugated bridge between an electron-rich central unit and electron-deficient end-capping groups and vice versa. On both trimers and pentamers, the effect of Tz orientation on the conjugation properties of the synthesized materials was investigated by a combination of experimental measurements and density functional theory calculations. This study highlights that control of the orientation of the Tz unit leads to the synthesis of the most conjugated regioisomer derivative. The present work gives chemical synthesis tools for the synthesis of selectively oriented Tz-based materials as well as a general guideline for the design of Tz-based materials with the highest conjugation length, including the Tz-orientation effect.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C30H43O2P, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 787618-22-8, in my other articles.
