Reduction of (Z)-β-butyltelluro-enones gives the corresponding γ-hydroxy vinylic tellurides with retention of the double bond configuration. Reaction of γ-hydroxy vinylic tellurides with 2 equiv of n-butyllithium produces 1,4-C,O-dianions, which on reaction with carbon dioxide give the corresponding butenolides.
(Z)-β-丁基碲-烯酮的还原得到相应的具有双键构型的γ-羟基乙烯基碲化物。γ-羟基乙烯基碲化物与2当量的正丁基锂反应生成1,4-C,O-二价阴离子,其在与二氧化碳反应后得到相应的丁烯化物。
