The reaction of oxophosphoranesulfenyl chlorides RR'P(O)SCl 2 with PIII compounds has been investigated.Its mechanistic features have been elucidated by variable-temperature 31P NMR spectroscopy and stereochemical changes at PIV and PIII phosphorus centers.These studies show that in all cases phosphonium intermediates containing the sulfur bridge >P(O)-S-P(+)P(S)-O-P(+)-Cl(-).The latter decomposes by the attack of the chloride anion on the thiophosphoryl center (deoxygenation pathway). 31P NMR studies fully corroborated the observed stereochemical changes.

The selectivity of sulphur, selenium and oxygen removal from pseudohalogens: phosphorus disulphides 1 and 2, diselenides 3 and oxophosphoranesulphenyl chlorides 4 has been investigated.A mechanistic rationalization is proposed to account for sulphur(selenium)/oxygen extrusion variation as a function of substrates structure and reaction conditions.
