allylsilane and an enamine. It exhibits enamine-type reactions with electrophiles leading to substituted β-trimethylsilyl aldehydes which are protected substituted acroleïnes. In contrast an allylslane-type reaction occurs upon treatment with ketones in the presence of fluoride ion. Aminoallylsilane (2) is inert towards electrophiles activated by Lewis acids, but fluoride ion activation of 2 promotes
由烯丙基吡咯烷制备(3-吡咯烷基烯丙基)三甲基硅烷(1)和(1-吡咯烷基烯丙基)三甲基硅烷(2)。化合物1既是烯丙基硅烷又是烯胺。它表现出与亲电子试剂的烯胺型反应,导致取代的β-三甲基甲硅烷基醛被保护的取代丙烯醛。相反,在氟离子存在下用酮处理后会发生烯丙戊烷型反应。氨基烯丙基硅烷(2)对被路易斯酸活化的亲电试剂呈惰性,但氟离子2的活化会促进与羰基化合物的反应,从而生成氨基醇和氨基呋喃的混合物。
