Sulfene complexes [CpRu(PRЈ 3 ) 2 (RHC=SO 2 )]PF 6 (2aϪd) are obtained from the corresponding sulfur dioxide complexes 1aϪc and diazomethane or -ethane. Reaction of [CpRu(dppm)(SO 2 )]Cl (1d) and phenyldiazomethane gives the chlorobenzylsulfinato complex [CpRu(dppm)(SO 2 -CHPhCl)] (3). Alternatively
