The lithio derivative of 2-diethylamino-4-phenylthio-2-butenonitrile is a practical equivalent of the unknown B-carboxyl-vinyl anion,as shown by its facile alkylation with alkyl halides, aldehydes and a-enones,followed by hydrolysis oxidation and elimination.
2-二乙基氨基-4-苯硫基-2-丁烯腈的硫代衍生物实际上等同于未知的B-羧基-乙烯基阴离子,表现为它易于与烷基卤化物,醛和α-烯酮进行烷基化,随后进行水解氧化和消除。
