The hydroboration of alkenes of diverse structural types by assorted N-heterocyclic carbene boranes can be accomplished by addition of 5-10% diiodine. For example, reaction of 1,3-dimethylimidazol-2-ylidene borane (diMe-Imd-BH3) with 10% I2 followed by addition of 2,3-dimethyl-2-butene provided the corresponding thexyl

Although indirect evidence has suggested that liver microsomal cytochrome P-450 can reductively dehalogenate several compounds to carbene metabolites, there has been no direct proof for the formation of these reactive species. We report in this paper that carbenes can be
