Notes:
The reaction of 4,5-dimethyl-2-phenylphosphinine with sulfur in boiling benzene in the presence of N-methylimidazole as a catalyst first yields a P-sulfide. This monosulfide further reacts with sulfur to give a diphosphinine trisulfide and a diphosphinine tetrasulfide. The X-ray crystal structure analysis of the trisulfide has been carried out.The two head-to-tail 1,6-dihydrophosphinine rings are connected by P—S—C and P—C links, thus forming a central 1,2,4-thiadiphospholane heterocycle. The P—C bridge is weak [1.881(3) Å] and sulfur can insert into it to give the symmetrical tetrasulfide with two P—S—C bridges.
