Silylcyanation of aldehyde or ketone was performed in a solution involving Et3SiCN produced by photoreaction of Et3SiH with MeCN in the presence of a catalytic amount of Cp(CO)2FeMe (Cp = C5H5). The iron complex derived from Cp(CO)2FeMe serves as a catalyst both for C–C bond cleavage of MeCN and concomitant Si–C bond formation and for Si–C bond cleavage in silylcyanation. The catalytic reaction mechanism has been discussed.

硅氰化反应是在一种溶液中进行的,该溶液通过Et3SiH与MeCN在催化量的Cp(CO)2FeMe(Cp =
C5H5)存在下的光反应生成Et3SiCN。来自Cp(CO)2FeMe的
铁复合物在MeCN的C–C键裂解及伴随的Si–C键形成、以及在
硅氰化反应中的Si–C键裂解中均作为催化剂。催化反应机制已被讨论。
