以2，4-二叔丁基-6-甲氧基苯基为保护基，合成了一种新型的二氯化亚磷，并将其转化为不对称二膦，再与硫反应，得到相应的硫代二膦和硫杂二膦。将二氯化亚磷还原成相应的伯膦，将其硫化成二硫代磷烷。二硫代膦与二苯甲酮反应生成硫代二苯甲酮。
A phosphonous dichloride carrying 2,4-di-t-butyl-6-methoxyphenyl as a novel sterically protecting group was prepared and converted to an unsymmetrical diphosphene, which reacted with sulfur to give the corresponding diphosphene sulfide and thiadiphosphirane. The phosphonous dichloride was reduced to the corresponding primary phosphine, which was sulfurized to a dithioxophosphorane. The dithioxophosphorane reacted with benzophenone to give thiobenzophenone.
