lene in the presence of a catalytic amount of the Brønsted acid o-benzenedisulfonimide under mild conditions to give good yields of the corresponding products. The catalyst can be easily recovered and purified for use in further reactions, which has economic and ecological advantages. homogeneous catalysis - Brønsted acid - Hosomi-Sakurai reaction - acetals - alcohols
在催化量的布朗斯台德酸邻苯二磺酰亚胺的存在下,各种缩醛或醇与烯丙基(三甲基)硅烷或1-苯基-2-(三甲基甲硅烷基)乙炔在温和的条件下反应,可得到相应产物的良好收率。该催化剂可以容易地回收和纯化以用于进一步的反应,这具有经济和生态优势。 均相催化-布朗斯台德酸-Hosomi-Sakurai反应-缩醛-醇
