Reduction of the carbonyl group in organomercurials can be carried out with retention of the mercury, provided it is protected by methylation. Thus, the bromomercurio aldehyde 6 is first methylated by MeCu to give 11, whose reduction with NaBH4, LiAlH(t-BuO)3, L-Selectride®, or superhydride® affords the alcohol 12. Mercury is then deprotected by treatment with HgBr2 (12 → 13). The resulting alcohol
