合成了硒氧硫代（2，4-二叔丁基-6-二甲氨基苯基）正膦，并与三二甲氨基膦脱硒，首次得到相应的硫代亚膦（硫代膦、硫代膦或硫代亚膦），它是一种热稳定的化合物，被认为是由邻二甲氨基的孤对电子稳定的。
Selenoxothioxo(2,4-di-t-butyl-6-dimethylaminophenyl)phosphorane was prepared and was deselenated with tris(dimethylamino)phosphine to give the corresponding phosphinothioylidene (thioxophosphine, thionophosphine, or phosphinidene sulfide), for the first time, as a thermally stable compound, which is considered to be stabilized with the lone pair electrons of the o-dimethylamino group.
