The methoxymercuration-demercuration reactions of all the methyl cis-undecenoates are reported. Oxymercuration reaction of acetylenic esters gives keto-and hydroxy-esters when demercurated with hydrochloric acid and sodium borohydride respectively. Similar reactions are carried out with methyl octad
