(diazomethane, enol ethers, and others). Their nucleophilic carbenoid precursors could be trapped by an electrophilic olefin (ketene dithioacetal S,S-dioxides as Michael acceptors). Stable carbene Z-dimers could be obtained under various conditions. Bromine catalyzed isomerization to E-isomers proved to be reversible.
有机硫代磺酰基卡宾通过碘的热解或从α-氯代α-有机硫代砜及其衍生物开始的α-消除反应生成。它们已被合适的亲核攻丝试剂(重氮甲烷,烯醇醚等)捕获。它们的亲核类胡萝卜素前体可能被亲电烯烃(烯酮二硫缩醛S,S-二氧化物作为Michael受体)捕获。可以在各种条件下获得稳定的卡宾Z-二聚体。溴催化异构化为电子异构体被证明是可逆的。
