在三乙胺存在下,鉮盐与苯硫基氯化物反应,然后与醛反应,产生相应的α-苯硫基-α,β-不饱和羰基化合物,构型以(Z)-型为主,产率良好.

关键词: 合成, 鉮盐, α-苯硫基-α,β-不饱和羰基化合物

Arsonium salts reacted with benzenesulfenyl chloridein the presence of triethylamine, followed by the Wittig reaction with aldehydes, predominantly giving (Z)-α-thiophenyl-α,β-unsaturated carbonyl compounds in good to excellent yields.

Key words: synthesis, arsonium salt, α-thiophenyl-α,β-unsaturated carbonyl compound
