I know we have not covered oxymercuration demercuration, but when we do could we go over the reduction mechanism between NaBH4 and the less substituted Mercury Acetate? Thanks. (First, H- replaces the acetate ligand at Hg, and then shifts to carbon, breaking both H-Hg and C-Hg bonds with possible intermediacy of the alkyl free radical (JACS, 1974, 96,3,870). - GS).
