Alkylation of silyl enolates with tert-alkyl or allylic fluorides proceeds smoothly in the presence of a catalytic amount of boron trifluoride to afford the corresponding carbonyl compounds. Allylation and reduction of alkyl fluorides with allylsilane and hydrosilane, respectively, occur under BF3 catalysis.
在催化量的三氟化硼的存在下,用叔烷基或烯丙基氟化物进行烯基甲酸酯的烷基化反应进行得很顺利,从而得到相应的羰基化合物。在BF 3催化下,烷基氟与烯丙基硅烷和氢硅烷的烷基化和还原反应分别发生。
