Reaction of three-coordinate phosphorus compounds with organophosphorus pseudohalogens. Part 4. The mechanism of interaction between bis(phosphinoyl) diselenides [R1R2P(O)Se]2 with three-coordinate phosphorus compounds

The reaction of bis(phosphinoyl) diselenides R1R2P(O)Se-SeP(O)R1R2 1 with P(III) compounds has been investigated and its mechanistic features have been elucidated by variable temperature 31P NMR spectroscopy. These studies show that in most cases phosphonium intermediates [>P(O)-Se-P+-O-P(Se)P(Se)-O-P+-O-P(Se)a phosphorane intermediate is observed. In the isomerization 7→10 and 13→16 the pathway of decomposition (deselenization, deoxygenation or dealkylation) to give stable end products is influenced by electronic and steric factors.
