Abstract

Abstract: Low-temperature 31P NMR spectroscopy and stereochemical data obtained from compounds having optically active phosphorus and carbon centers have been applied to elucidate the mechanism of the reaction between phosphorus thionoesters> P (S) OR (1) and chlorine or sulfuryl chloride. Phosphonium intermediates were unambiguously detected and depending on the substituent at the phosphorus atom may or may not undergo ...
