Abstract

Several 3‐phosphabicyclo[3.1.0]hexane 3‐oxides have been transformed into the corresponding sulfides by reaction with phosphorus pentasulfide. The 3‐phenyl derivative could also be prepared by deoxygenation of the oxide followed by reaction with elemental sulfur. Opening of the cyclopropane ring in phosphabicyclohexane sulfides afforded mixtures of 3‐ and 5‐methyl‐1,2‐dihydro‐phosphinine‐1‐sulfides. Because of better yields, preparation of these products by thionation of the dihydrophosphinine oxides is more appropriate. The new phosphorus heterocycles have been characterized by 31P, 13C, and 1H NMR and mass spectral data.
