to be an efficient catalyst for allylation and cyanation of aldehydes with allyltrimethylsilane and trimethylsilyl cyanide in the presence of acetic anhydride at room temperature to produce homoallylic acetates and α-cyano acetates in excellent yields. A solution of 10 mol % of LiBF4 in acetonitrile provides a convenient reaction medium to carry out allylation and cyanation reactions under very mild
发现四氟硼酸锂是在室温下在乙酸酐存在下用烯丙基三甲基硅烷和三甲基甲硅烷基氰化物将醛与烯丙基化和氰化的有效催化剂,以优异的收率生产均相乙酸酯和α-氰基乙酸酯。LiBF 4在乙腈中的10 mol%的溶液提供了一种方便的反应介质,可以在非常温和和中性的条件下进行烯丙基化和氰化反应。
