Reaction of manganic acetate with diphenyidisulplilde in dichloromethane-trifluoroacetic acid in the presence of allylic esters or amides of allylamine gives trifluoroacetoxysulphides and hence by ready hydrolysis vicinal hydroxysulphides. The regiochemical outcome can be controlled by selection of either an acetyl- or trifluoroacetyl derivative.
在烯丙基胺的烯丙基酯或酰胺的存在下,乙酸锰与二苯甲二硫在二氯甲烷-三氟乙酸中的反应产生三氟乙酰氧基硫化物,并因此通过易水解的邻位羟基硫化物进行反应。可以通过选择乙酰基或三氟乙酰基衍生物来控制区域化学结果。
