Abstract: Addition-elimination of an alcohol to 1, 2-bis (phenylsulfonyl) ethylene afforded b- alkoxyvinyl sulfones which were submitted to reductive elimination with 6% sodium amalgam to produce the corresponding ethenyl ethers in high yields and purity. Key words: b-alkoxyvinylsulfones, ethenyl ethers, bis (phenylsulfonyl) ethylene, reductive desulfonylation
