Treatment of diazo mercaptans with rhodium(II) acetate gives six- and seven-membered sulphur heterocycles; diazo sulphides give cyclic sulphonium ylides, which are isolable, or rearrange, depending on the nature of the substituent on sulphur.

Treatment of diazo sulphides with rhodium (II) acetate in benzene gives six- and seven-membered cyclic sulphonium ylides; although the S-benzyl and S-ethyl ylides can be isolated, they rearrange, or eliminate ethylene respectively, on heating; the S-allyl ylides cannot be isolated since they undergo spontaneous -sigmatropic rearrangement.
