Phosphorylated, silylated, and stannylated derivatives of alpha-mercaptocarbonyl compounds

The authors are summing up their research in the held of phosphorylation, s ilylation, and stannylation of alpha -mercaptocarbonyl compounds. Synthetic methods were developed for a series of new saturated and unsaturated organ osilicon(tin) reagents that were applied to organophosphorus syntheses. Rep resentatives of new classes of heterocyclic compounds were prepared: 1,3,2- oxathiaphospholenes with four- and five-coordinate phosphorus. A new thioph osphite-thiophosphate rearrangement initiated by molecular oxygen was disco vered.
