[1,3,4]THIAZAPHOSPHOLIDINE III

Abstract

Bis(diethylamino)phosphanylacetylene and N,N'-dimethyl thiourea react to give the [1,3,4]thiazaphospholidine 3. Chemical reactions of 3 with various reagents lead to six other members of the title compound class. With LiAlH₄ 3 forms the primary phosphine 12. By heating 3 is transformed into the [1,4,2]diazaphospholidine 4. All new compounds are characterized by their nmr, ir, and mass spectra.
