γ,δ-Unsaturated γ-sulfenyl or sulfinlalkylmercury chlorides 5 and 15, generated from the cyclopropyl sulfide 7 and mercury (II) trifluoroacetate, were demonstrated to be homoallyl anion synthons; these compounds recyclized into the α-functionalized cyclopropyl sulfide on reaction with several electrophiles.
由环丙基硫醚 7 和三氟乙酸汞 (II) 生成的δ,δ-不饱和δ-亚磺酰基或亚磺烷基汞氯化物 5 和 15 被证明是同烯丙基阴离子合成物;这些化合物在与几种亲电物反应时再生成δ-官能化环丙基硫醚。
