N2 - Reaction of (diphenylmethylene)(2,4,6-tri-t-butylphenyl)phosphine with elemental sulfur afforded 3,3-diphenyl-2-(2,4,6-tri-t-butylphenyl)-1,2-thiaphosphirane 2-sulfide via methylenephosphine P-sulfide. Desulfurization reaction of the thiaphosphirane 2-sulfide with tris(dimethylamino)phosphine gave 3,3-diphenyl-2-(2,4,6-tri-r-butylphenyi)-l,2-thiaphosphirane. Valence isomerization occurred between the methylenephosphine P-sulfide and the thiaphosphirane by heat or by photo-irradiation. The structures of the methylenephosphine, the methylenephosphine P-sulfide, and the thiaphosphirane were analyzed by X-ray crystallography.
