The stereochemistry of acetoxymercuration of 3-hexyne has been established as antarafacial on the basis of an X-ray crystallographic study. Acetoxymercuration of diphenylacetylene afforded (Z)-cY-acetoxy-8-(acetoxymercuri) stilbene by a suprafacial addition of Hg (OAc)? A simple method for the in situ acetoxymercurationdemercuration of dialkyl-substituted alkynes to afford vinyl acatatea is deacribed. The sodium borohydride ...
