Reactivity of Conjugated Bases of Hydridophosphoranes. Synthesis of Unusual Phosphoranes Bearing P-S⁻, P-Se⁻, P-P-S⁻ and P-N- as Exocyclic Bonds

Abstract

Triethylammonium salts of spirophosphoranes having P-SH, P-SeH, P-P-SH and P-NH- bonds were prepared by reaction, in presence of triethylamine, of hydridophospho-ranes on sulfur, selenium, Lawesson's reagent, tosylazide. With trimethylchlorosilane, trico-ordinated compounds was obtained instead of pentaco-ordinated derivatives.
