Phosphino sulphonates, a type of PIII-anhydride and their isomerisation into phosphinoyl sulphinates: a novel rearrangement in phosphorus–sulphur chemistry
Abstract
The imidazolides (1) react smoothly with RSO3H to afford a novel class of trico-ordinate phosphorus anhydride, the phosphino sulphonates (2); under sutable structure circumstances the compounds (2) undergo a novel type of rearrangement, (2)→(6), which provides the first example of a phosphinoyl sulphinate structure (6).
