and Michael reactions of silyl enol ethers with carbonyl compounds or other electrophiles (trimethyl orthoformate, dimethyl acetal, and chloromethyl methyl ether), the allylation reaction of allylsilanes with aldehydes, and the Diels–Alder reaction of dienes with α,β-unsaturated aldehydes. A solution of formaldehyde in water is applicable as an electrophile. Also, the aldol-type reaction of ketene silyl
三(五氟苯基)硼是一种高效、空气稳定且耐水的路易斯酸催化剂,用于甲硅烷基烯醇醚与羰基化合物或其他亲电子试剂(原甲酸三甲酯、二甲基乙缩醛和氯甲基甲基醚)的羟醛型和迈克尔反应,烯丙基硅烷与醛的烯丙基化反应,以及二烯与 α,β-不饱和醛的 Diels-Alder 反应。甲醛水溶液可用作亲电子试剂。此外,烯酮甲硅烷基缩醛与芳香族或脂肪族亚胺的羟醛型反应也使用相同的催化剂成功进行。
