structure of the major diastereomer formed in the chlorination of (+)-(S)-1ai.e. (+)-(S)c(S)s-α-chloro-α-dimethoxyphosphorylmethyl p-tolyl sulfoxide 2a was determined by X-ray analysis. The structure was solved by direct methods and refined to R=0.081. The experimental data on chlorination of α-phosphoryl sulfoxides 1 point to retention of the configuration at both chiral centres (C and S) and this stereochemistry
