Dimethyl disulfide traps organometallic species very effectively. For example, it converts the poorly soluble lithium 3-lithio-2-naphthoate into 3-methylthio-2-naphthol in 83% yield. Treated with the same reagent, iV,0-dilithiated ter/-butyl- -phenyl-carbamate furnishes the methyl sulfide in 89% yield. The smelly workup can be avoided if dimethyl disulfide is replaced by diphenyl disulfide, sulfur di-chloride, or di(benzenesulfonyl)sulfide. Particularly clean reactions are achieved with thio-A,A -diimidazole (83, Scheme 1-58). ...
