Treatment of diazo sulphides with rhodium (II) acetate in benzenegives six- and seven-membered cyclic sulphoniumylides; 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 [2,3]-sigmatropic rearrangement.

Rhodium (II) acetate catalysed decomposition of the diazo sulphoxides(1) and (3) gives the cyclic sulphoxonium ylides (2) and (4); the structures of (2c) and (4a) were confirmed by X-ray crystallography.

Rhodium carbenoid mediated cyclisations. Part 5. Synthesis and rearrangement of cyclic sulphonium ylides preparation of 6- and 7-membered sulphur heterocycles

日期:1990.1
Treatment of diazo mercaptans with rhodium(ll) acetate gives six- and seven-membered sulphur heterocycles; diazo sulphides give cyclic sulphoniumylides, which are isolable, or rearrange, depending on the nature of the substituent on sulphur.
