Summary Sulphonylation of p-hydroxy selenides, pre- PhSeNa,8 or by reaction of cc-lithio selenides 9J0 and selen- pared by addition of organometallic compounds to oxideslO with carbonyl compounds. We have used ali- carbonyl compounds, results in reductive elimination to phatic selenides as starting materials since these are readily give olefins under unusually mild conditions. ...
