Abstract

We report the iridium-catalysed desilylative acylation of styryl and dienyl silanes by acid anhydrides to afford (E)-α,β-unsaturated ketones. The [{Ir(μ-Cl)(cod)}₂] catalyst is the first non-rhodium complex successfully applied for this type of transformation. Stoichiometric reaction of [{Ir(μ-Cl)(cod)}₂] with (E)-trimethyl(4-chlorostyryl)silane was carried out to gain insight into the reaction mechanism.

铱催化1-烯基硅烷的脱苯酰基化反应

我们报道了铱催化苯乙烯基和二烯基硅烷在酸酐作用下的脱硅酰化反应，得到(E)-α，β-不饱和酮。[{Ir(μ-Cl)(cod)}2]催化剂是第一个成功应用于此类转化的非铑配合物。研究了[{Ir(μ-Cl)(cod)}2]与(E)-三甲基(4-氯苯乙烯基)硅烷的化学计量反应，探讨了反应机理。
