Fluoride ion-induced desilylation of (E)-2-trimethylsilylalk-2-enenitriles affords(Z)-1-cyanoalk-1-enyl anion intermediates, which are trapped by carbonyl compounds to give (E)-2-(1-hydroxyalkyl)alk-2-enenitriles with 100% retention of the configuration.
氟离子诱导的(E)-2-三甲基甲硅烷基烷基-2-烯腈的甲硅烷基化反应生成(Z)-1-氰基烷基-1-烯基阴离子中间体,被羰基化合物捕获,得到(E)-2-(1-羟烷基) )烷基-2-乙腈,具有100%的构型保留率。
