(2,4-Pentadienyl)- and (2,4-hexadienyl)trimethylsilanes, prepared from the corresponding pentadienylpotassiums and trimethylchlorosilane, react smoothly with various electrophiles such as acetals, aldehydes and acid halides to give pentadienylation products, with regiospecific transposition of the pentadienyl group.
由相应的戊二烯基钾和三甲基氯硅烷制得的(2,4-戊二烯基)-和(2,4-己二烯基)三甲基硅烷与各种亲电子试剂(如乙缩醛,醛和酰卤)平稳反应,生成戊二烯化产物,并通过戊二烯基的区域特异性转位团体。
