A simple reaction affording (E)-1-dimethylamino-2-phenylsulfonylethylene, and S-((E)-2-(N′N′-dimethylamino)ethenyl)-5-phenyl-N-(p- tolylsulfonyl) sulfoximide in high yields is described. A reversal in regioselectivity was observed when the ss-dimethylamin

Reactions of 1-lithio-1-phenylthiomethyl- (1a) and 1-lithio-1-methylthiomethyltrimethylsilane (1b) with amides, an ester, acid anhydrides, a urea, and a carbonate are described which provide useful routes to functionalized vinyl sulfides.The reaction of 1 with amides gave β-functionalized vinyl sulfides, 1-dialkylamino-2-phenylthio (or methylthio)ethylenes, in 40-95percent yields and the reaction could be extended to the sulfonyl derivatives of 1 to afford 1-dialkylamino-2-phenylsulfonyl(or methylsulfonyl)ethylenes.Although ethyl benzoate and some acid anhydrides were not good substrates for this reaction, tetramethylurea and diethyl carbonate gave α-functionalized vinyl sulfides, 1-amidovinyl- and 1-(ethoxycarbonyl)vinyl sulfides, in moderate yields when treated with 1a followed by addition of benzaldehyde.

The reaction of phenoxyvinyl sulfones with strongly basic aliphatic amines and hydrazines takes place with substitution of the phenoxy group.As a result of the reaction trans-dialkylaminovinyl sulfones and β-phenylsulfonylacetaldehyde hydrazones are obtai
