B-C bond cleavage and ru-C bond formation from a phosphinoborane: Synthesis of a bis-σ borane aryl-ruthenium complex

Compared with the reactivity of o-Ph2P(C6H4-CH2)BH(NiPr2) with [RuH2(η2-H2)2(PCy3)2], the behavior of the phosphinoborane Ph2P(CH2-C6H4)BH(NiPr2) is radically different. No agostic σ-B-H complex could be observed, the reaction leading to the isolation of a new bis-σ borane aryl-ruthenium complex via B-C bond cleavage and Ru-C bond formation. Reactivity studies of this complex with dihydrogen and/or HBArF4 as a proton source enable the formation of a tethered chiral-at-Ru piano-stool cationic complex.

Visible-Light-Promoted Unsymmetrical Phosphine Synthesis from Benzylamines

Herein, by applying visible-light photoredox catalysis, we have achieved the catalytic deaminative alkylation of diphenylphosphine and phenyl phosphine with benzylamine-derived Katritzky salts at room temperature. The use of Eosin Y as photoredox catalyst and visible light can largely promote the reaction. A series of unsymmetrical tertiary phosphines were successfully synthesized, including phosphines with three different substituents that are otherwise difficult to obtain.

Rationale for the sluggish oxidative addition of aryl halides to Au(I)

The oxidative addition of Csp2-Br or C sp2-I bonds to gold(i) does not take place even under very favorable intramolecular conditions that could form five- or six-membered gold(iii) metallacycles. DFT calculatio

HYDROFORMYLATION CATALYSTS

This invention is directed to a class of compounds that can be both monodentate and bidentate in their association with a transition metal to form a catalyst for reactions such as the hydroformylation of olefins to produce aldehydes. The compounds contain two phosphorus atoms having different steric and/or electronic nature. In hydroformylation catalysts, the compounds advantageously can produce a variable n/iso product mixture of aldehyde products that can be varied by simply changing process variables such as [H2]/[CO] partial pressure gas ratio or temperature/inert gas partial pressure.

Facile Photochemical Synthesis of Benzylphosphines

Facile large-scale synthesis of the benzyl-dibromo-phosphines RPBr2 (R = C6H5CH2, 3,5-Me2C6H3CH2, 2-BrC6H4CH2) is accomplished by the photochemical reaction of toluene, mesitylene and 2-bromotoluene, respectively, with PBr3 in the absence of solvent.It the reactions are carried out up to 50percent completion the amount of by-products formed is remarkably low, rarely exceeding 10percent of the total amount of products formed.The selectivity of the photoreaction may be improved up to 98percent if it is carried out in a modified Soxhlet apparatus which allows the predominant irradiation of only the starting materials.The apparent limitations imposed by the low turnovers required to achieve good products formed in a short period of time and by the easy recovery of unreacted starting material by distillation.Thus in the case of 2-BrC6H4CH2PBr2, in a typical run 94 g (261 mmol) of product may be isolated after 2.5 h of irradiation of 970 mmol of 2-BrC6H5CH3 and 1.39 mol of PBr3.In this case the turnover is 32percent, the isolated yield 27percent, and the by-product 2-methylphenyl-dibromo-phosphine only amounts to less than 2percent.The benzyl-dibromo-phosphines are easily methylated with two equivalents of MeMgCl to give the respective benzyl-dimethyl-phosphines in 79-93percent yield.Tertiary benzylphosphines MePRR' (R = 2-BrC6H4CH2, R' = Me3SiCH2; R = R' = 2-BrC6H4CH2) are obtained in easy one-pot syntheses by consecutive reactions of 2-BrC6H4CH2PBr2 with Me3SiCH2MgCl and MeMgCl, and with 2-BrC6H4CH2MgBr and MeMgCl, respectively. - Keywords: Benzylphosphines, Photochemical Synthesis
