Suitably substituted twisted push-pull ethylenes capable of existing either as mixtures of achiral diastereoisomers or as pairs of enantiomers have been resolved, in the first case into diastereoisomers by HPLC on silica, in the second case into enantiome

When 6,6-dimethyl- and 6-phenyl-3-thioxo-6,7-dihydro-3H-1,2-benzodithiol-4(5H)-one was allowed to react with monomeric boron trisulphide under argon, the only products isolated after chromatography on silica were the corresponding S-oxides in up to 37perc
