The Lewis acid-catalyzed reactions of olefins with chloromethoxymethane (CM) or dimethoxymethane (DM) and aliphatic or aromatic nitriles afforded the 1 : 1 : 1 adducts and/or their hydrolysis products in various yields, together with the 1 : 1 olefin–CM (or DM) adducts. AlCl3, FeCl3, ZnCl2, and SnCl4 were effective catalysts for the reaction with CM, whereas BF3 and SnCl4 were effective for that with
烯烃与氯甲氧基甲烷 (CM) 或二甲氧基甲烷 (DM) 和脂肪族或芳香族腈的路易斯酸催化反应得到 1 : 1 : 1 加合物和/或它们的不同产率的水解产物,以及 1 : 1 烯烃-CM (或 DM)加合物。AlCl3、FeCl3、ZnCl2 和 SnCl4 是与 CM 反应的有效催化剂,而 BF3 和 SnCl4 是与 DM 反应的有效催化剂。在环己烯的情况下,加成以反式进行;即,甲氧基甲基和腈分子从相反侧加到烯烃上。
