Phosphorus ni Compounds

Thiiranes such as 2-methylthiirane and epithiocyclohexane, catalyzed by rhenium complexes, are useful reagents for sulfurization of phosphorus(iii) compounds (Equation (32) Table 3) <1997TL7701>. Mild reaction conditions and a short reaction time make this method of sulfurization of phosphorus(ni) compounds most interesting. Possible mechanisms for the rhenium-catalyzed sulfurization of phosphorus(lll) compounds are outlined in Scheme 38.
