Reaction of chloroform with acrylic esters 1a-g, carried out in the presence of 50% aq NaOH, benzyltriethylammonium chloride (TEBACl) as a catalyst in heptane, gives exclusively adducts of trichloromethyl anion 2a-g with good yields. The same reaction carried out in the absence of solvent yields a mixture of products.
氯仿与丙烯酸酯1a-g的反应在庚烷中作为50%NaOH水溶液,苄基三乙基氯化铵(TEBACl)作为催化剂存在下进行,仅得到三氯甲基阴离子2a-g的加合物,收率很高。在没有溶剂的情况下进行的相同反应产生产物的混合物。
