cyanosilylation was achieved by the reaction of chlorodiphenylsilyl ether of homopropargylic alcohols with trimethylsilylcyanide in the presence of palladium catalyst. The reaction proceeded regio- and stereoselectively to give (Z)-3-(1-cyanoalkylidene)-2-silatetrahydrofurans, whose silyl group was transformed into various organic groups.
分子内的氰基硅烷化反应是通过在钯催化剂存在下,均炔丙基醇的氯二苯基甲硅烷基醚与三甲基甲硅烷基氰化物反应来实现的。反应进行区域和立体选择,得到(Z)-3-(1-氰基亚烷基)-2-硅四氢呋喃,其甲硅烷基被转化成各种有机基团。
