Treatment of diazo mercaptans with rhodium(ll) 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.
用乙酸铑(II)处理重氮硫醇,得到六元和七元硫杂环。重氮硫化物可生成环状sulph,它们可分离或重排,具体取决于硫上取代基的性质。
