Reactions of alkenes with di-n-propyl, diphenyl, and dibenzyl disulphide in the presence of lead(IV) salts in trifluoroacetic acid-dichloromethane are described. The products, vicinal trifluoroacetoxy-sulphides, are obtained in higher yields with manganese (III) salts as the oxidant. Alternative reaction conditions with use of iron(III) salts or in the absence of added metal salts are also described
描述了在三氟乙酸-二氯甲烷中铅(IV)盐存在下烯烃与二正丙基,二苯基和二苄基二硫化物的反应。用锰(III)盐作为氧化剂,可以以较高的产率获得邻位的三氟乙酰氧基-硫化物。使用铁的替代反应条件(III还描述了)盐或不存在添加的金属盐的情况。在Ritter条件下,衍生自二苯基二硫化物的三氟乙酰氧基硫化物与乙腈反应,生成乙酰胺基硫化物,但是衍生自苄基乙酰胺的另一种反应途径,衍生自二苄基二硫化物的三氟乙酰氧基硫化物仅以较差的产率得到邻位乙酰酰胺基硫化物。描述了乙酰氨基硫化物到氨基硫化物和乙酰氨基硫醇的转化。
