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.
