An enantiopure phosphonothioic acid showed a unique and superior chiral recognition ability, arising from its P-stereogenicity, for racemic 1-phenylethylamine derivatives through diastereomeric crystallization. Spherical molecular clusters, associated by hydrogen bonds and CH/pi interactions, aggregated with high symmetry in the less-soluble diastereomericsalts.

The preparation and base solvolyses of some S-phosphorylated derivatives of 2-mercaptoethanol and related compounds are reported. The fully esterified derivatives possessing favourable stereochemistryrearrange to the O-phosphorylated derivatives which then undergo elimination of an episulphide. In contrast, the mono-esterified derivatives eliminate alkoxide to give the cyclic intermediate [graphic
Catalysis by metalloporphyrins of oxidative desulphurisation at pentacovalent phosphorus by cumyl hydroperoxide

Cumylhydroperoxide causes oxidative desulphurisation at pentacovalent phosphorus with retention of configuration in the presenceof various manganese (iii) and iron (ii) mesotetraphenylporphyrins provided imidazole is present, the yields of oxidised phosphorus compounds being influenced by the rate of destruction of the hydroperoxide by parasitic side reactions.
