  羧酸与硅烷脱氢偶联反应的两种新型催化剂——原子经济制备甲硅烷酯的简便方法

  摘要：

  摘要 三（三苯基膦）氯化亚铜 [Cu(PPh3)3Cl] 已被发现是羧酸与硅烷脱氢硅烷化的有效催化剂。在 4 mol% Cu(PPh3)3Cl 存在下，乙腈中的脱氢硅烷化反应在 80°C 下以良好的产率得到相应的甲硅烷基酯。注意到三苯基膦本身也用作反应的适当催化剂。

  Triphenylphosphine has been found to be an efficient catalyst for the dehydrosilylation of carboxylic acids with silanes. In the presence of 4 mol % of triphenylphosphine (PPh3), dehydrosilylation reactions in DMF afforded the corresponding silyl esters at 120 °C in good yield.

  Abstractmagnified imageDinuclear metal complexes, especially (p‐cymene)ruthenium dichloride dimer [RuCl2(p‐cymene)]2}, have been found to exhibit high catalytic performance for the dehydrosilylation of various kinds of carboxylic acids and alcohols. The dehydrosilylation with [RuCl2(p‐cymene)]2 proceeded efficiently with only one equivalent of silane with respect to substrate (carboxylic acids or alcohols) under solvent‐free conditions to give the corresponding silyl esters and ethers in excellent yields with a high turnover number (TON) and frequency (TOF). The 1H NMR spectrum of a toluene‐d8 solution of [RuCl2(p‐cymene)]2 and a silane showed a signal assignable to the ruthenium hydride species. In contrast, no new signals were detected in the 1H NMR spectrum of a toluene‐d8 solution of [RuCl2(p‐cymene)]2 and a carboxylic acid or an alcohol. Therefore, the ruthenium metal in [RuCl2(p‐cymene)]2 activates a silane to afford the hydride intermediate, possibly a silylmetal hydride species. Then, the nucleophilic attack of a substrate (carboxylic acid or alcohol) to the hydride intermediate proceeds to give the corresponding silylated product. The present dehydrosilylation with an optically active silane proceeded exclusively under inversion of stereochemistry at the chiral silicon center, suggesting that the nucleophilic attack of a substrate to the hydride intermediate occurs from the backside of the ruthenium‐silicon bond.
