The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8, name: 1,1-Bis(diphenylphosphino)ferrocene

Compounds of the types ReOCl3(L-L) and ReOCl2(OEt)(L- L) with bis(diphenylphosphino)ethene (dppen) and bis(diphenylphosphino)ferrocene (dppf) were prepared by reacting the diphosphine with ReOCl 3(OPPh3)(Me2S). The ReOCl3(L-L) compound with bis(diphenylarsino)ethane (dpae) was prepared similarly. Crystallographic work on ReOCl3(dppen) and ReOCl3(dpae) confirmed the approximate octahedral environment of the metal and the presence of a Cl ligand trans to the Re=O bond. The ReOCl2(OEt)(L-L) compounds contain a transO=Re-OEt unit. The visible spectra of both types of compounds include a two-component d-d absorption pattern originating from the spin-allowed excitation of a d electron from the interaxial d orbital in the equatorial plane to the empty dxz and dyz orbitals. For ReOCl 2(OEt)(dppf), these bands are masked by strong transitions taking place in the ferrocene moiety. The absorptions of the other systems are not greatly displaced compared to the similar dppe compounds, a small decrease in the transition energy being noted for the dpae complex.

12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2, belongs to chiral-phosphine-ligands compound, is a common compound. In a patnet, once mentioned the new application about 12150-46-8, category: chiral-phosphine-ligands

New compounds Ia-h of the form [(Me2SO)ClPt(HR2DTO kappa-S,S Pt)] (HR2DTO = secondary dithiooxamide, with R = methyl, ethyl, n-propyl, n-butyl, n-decyl, isopropyl, (R)-1-phenylethyl, or (S)-2-hydroxypropyl; kappa-S,S Pt denotes the coordination of the DTO moiety to the Pt atom) have been prepared and used to synthesize platinum(II)/ferrocene dimetallic species IIa-h of formula [(dppf)Pt(HR2DTO kappa-S,S Pt)]Cl (dppf = 1,1?-diphosphinoferrocene). Complexes IIa-e, bearing unbranched groups on the dithiooxamide moiety (i.e., R = methyl, ethyl, n-propyl, n-butyl, or n-decyl groups), self-assemble upon standing to form unprecedented hexameric macrocycles IIIa-e. Compounds IIa-e, IIIa-e, as well as IIf-h, have been characterized by a combination of 1H, 13C, 31P NMR spectroscopy and 2D-ROESY and diffusion-ordered NMR spectroscopy (DOSY) experiments; the latter experiments have been used to calculate the hydrodynamic radius of IIa-e and IIIa-e, assisted by the data provided by the X-ray crystal structure of IIh. Compounds IIIa-e are characterized by the presence of six dppf bridging units occupying the inner rim of the macrocycles and exhibit interesting properties, for example, oxidation of IIIa-e occurs around +0.40 V versus saturated calomel electrode (SCE), whereas oxidation of the type II species occurs at potentials greater than +1.0 V. Oxidation of IIIa-e is explained through a delocalized orbital extending over the six dppf subunits. The reversibility of the self-assembly process is finally demonstrated by alternate addition of acids and bases to the type III compounds. Dimetallic building blocks containing PtII dithiooxamide and ferrocene subunits self-assemble in solution to generate unprecedented hexameric macrocycles that have peculiar geometrical, spectroscopic, redox, and reactivity properties. The self-assembly process is reversible and can be repeated at will by alternating suitable inputs.

Reactions of Fe3(CO)12 with the heterocycles phenazine and acridine in refluxing benzene afforded the mononuclear complexes Fe(CO)3(eta4-C12H8N2) (1a) and Fe(CO)3(eta4-C13H9N) (1b), respectively. Treatment of 1a with P(OMe)3 and PPh3 in the presence of Me3NO at room temperature yielded the carbonyl substitution products Fe(CO)2{P(OMe)3}(eta4-C12H8N2) (2a) and Fe(CO)2(PPh3) (eta4-C12H8N2) (3a), respectively. Similar reactions of 1b yielded Fe(CO)2{P(OMe)3}(eta4-C13H9N) (2b) and Fe(CO)2(PPh3) (eta4-C13H9N) (3b). Treatment of 1a with the diphosphines dppm and dppf under similar conditions afforded the mononuclear compounds Fe(CO)2(kappa1-dppm) (eta4-C12H8N2) (4a) and Fe(CO)2(kappa1-dppf) (eta4-C12H8N2) (4b). Compounds 1a, 2a, 3b, and 4a have been structurally characterized by X-ray crystallography. The ancillary phenazine and acridine ligands in these products adopt an eta4-coordination mode by using only the peripheral carbon atoms in one of the carbocyclic rings. Given the rarity of this coordination mode in metal carbonyl complexes, we have performed electronic structure calculations on 1a, and these data are discussed relative to the solid-state structure.

Two new heterobimetallic ruthenium (II) complexes with general formula [Ru(N-S)(bipy)(dppf)]PF6 (bipy = 2,2?-bipyridine, N-S = 2-mercaptothiazolinate ? mctz? (1) and 2-mercaptobenzothiazolinate ? mcbtz? (2); dppf = 1,1?-bis{diphenylphosphino}ferrocene) were synthesized from the reaction of cis-[RuCl2(bipy)(dppf)] and 2-mercaptothiazoline (Hmctz) or 2-mercaptobenzothiazoline (Hmcbtz), in the presence of triethylamine (NEt3) and KPF6 in MeOH, under reflux. The complexes were characterized by NMR (31P{1H}, 1H and 13C), vibrational spectroscopy (FTIR), cyclic voltammetry, molar conductivity, UV-Vis and elemental analysis (%C, %H, %N, and %S). Furthermore, the molecular structure of complexes 1 and 2 were solved by X-ray diffraction studies. UV-Vis spectroelectrochemistry studies were carried out for complex 2 in order to unravel the processes observed in the cyclic voltammetry. DFT analysis of complexes 1, 2 and the precursor complex cis-[RuCl2(bipy)(dppf)] revealed the composition of the frontiers orbitals, supporting the assignment of the electrochemical behavior of the complexes. The antibacterial potential of the new complexes and the free ligands (dppf, mctz? and mcbtz?) were assessed in vitro against Staphylococcus aureus, Staphylococcus epidermidis, E. coli and P. aeruginosa. The 1,1-diphenyl-2-picrilhidrazyl (DPPH) radical scavenging ability (antioxidant activity) was also evaluated.

In a Article，once mentioned of 12150-46-8, Computed Properties of C34H28FeP2

The regioselectivity of the palladium-catalyzed cyclization of propargylic carbonates with sulfonamide nucleophiles is critically dependent on the bite angle of the bidentate phosphine ligand. Ligands with small bite angles favor attack on the central carbon atom of an allenylpalladium intermediate to afford cyclic dienamide products, whereas the use of those with large bite angles leads to alkynyl azacycles, with high stereoselectivity. A computational analysis of the reaction pathway is also presented. Chomp! The bite angle of bidentate phosphine ligands determined the course of the palladium-catalyzed cyclization of propargylic carbonates with sulfonamide nucleophiles. A small bite angle favored attack on the central C atom of the allenylpalladium intermediate, whereas alkynyl azacycles were formed from attack on the terminal C atom using ligands with a large bite angle.

The first example of the thiyl radical promoted ligand-free iron-catalyzed oxidative cleavage of alkenes using molecular oxygen (1 atm) has been developed. The reaction proceeds under mild reaction conditions with high efficiency and high chemo- and regioselectivity. It features a broad substrate scope and excellent functional group compatibility, enabling facile access to valuable molecules for application in medicinal chemistry. Preliminary mechanistic studies reveal that a vital intermediate dioxetane might be involved in the reaction and a thiyl radical plays a synergistic role in facilitating the selective oxidation of the CC bond.

Allylic alcohols and allylic amines were directly utilized in a Pd-catalyzed hydrogen-bond-activated allylic amination under mild reaction conditions in the absence of any additives. The cooperative action of a Pd-catalyst and a hydrogen-bonding solvent is most likely responsible for its high reactivity. The catalytic system is compatible with a variety of functional groups and can be used to prepare a wide range of linear allylic amines in good to excellent yields. Furthermore, this methodology can be easily applied to the one-step synthesis of two drugs, cinnarizine and naftifine, on a gram scale.
