Methylthio- and methoxy-substituted allenylmethylsilanes, a kind of allylsilanes, undergo the ene-type reaction, not the usual allylsilane-type reaction accompanying by desilylation, with carbonyl and azo compounds mediated by a Lewis acid. The corresponding 1-silyl-substituted functionalized 1,3-dienes are obtained in good yields.
甲硫基和甲氧基取代的烯丙基甲基硅烷是一种烯丙基硅烷,它与路易斯酸介导的羰基和偶氮化合物进行烯类反应,而不是伴随甲硅烷基化反应的通常的烯丙基硅烷类反应。以良好的产率获得相应的1-甲硅烷基取代的官能化的1,3-二烯。
