✦ Synopsis

The react&em of rulfenes (geaeratedln situ frou alkanesulfa@chlorides aud triethylaulne) uith "electrcm-rich" olafins such as enauiaes 1*2, ketene acetalm3, ketene O.lLace- tals, snd ketone IlJi-acetals4 have been Investigated extensively. gillilarlyketenesreactlIith like olefins such as enauines to give cycloadducts 5.6 . Since the related ynauiaes have been found to undergo cycloadditiou reactiamTvith carbouyl campounds aud their idnes, l&-dipoles, and polar acetylenic emd olefinic bonds, their reactions with sulfenes and ketenes uere lnvestigated and are reported herein.
