Carbenes are known for their ability to abstract HCl from hydrochlorosilanes to form carbene hydrochloride adducts. In contrast, the Si–H bond insertion products RSiCl2(cAACH) (2, 4, 6, and 8) have been formed in the reaction of RSiHCl2 [R = Ar(SiMe3)N (1), Cp* (3), PhC(NtBu)2 (5), Cl (7); Ar = 2,6-iPr2C6H3] with a cyclic alkyl(amino) carbene (cAAC:) irrespective of the steric demand of the R group
卡宾因从氢氯硅烷中提取HCl形成卡宾盐酸盐加合物的能力而闻名。相反,Si-H键的插入产品RSiCl 2(cAACH)(2,4,6,和8)已经形成在RSiHCl的反应2 [R =氩(森达3)N(1)中,Cp *(3),PhC(N t Bu)2(5),Cl(7); Ar = 2,6- i Pr 2 C 6 H 3与环状烷基(氨基)卡宾(cAAC :)无关,而与R基团的空间需求无关。新产品的特征在于各种分析工具,包括X射线晶体学,电子电离质谱和NMR光谱。还进行了理论研究,以了解为什么cAAC偏爱插入Si-H键而不是脱卤化氢的途径。
