Lithium carboxylic acid enediolates are generated efficiently using lithium amides prepared from thienyllithium or butyllithium and either diethylamine, piperazine, N,N′-dibenzylethylenediamine, N-benzylpiperazine or 1,3,3-trimethyl-6-azabicyclo[3.2.1]octane, even in catalytic amounts.
使用由噻吩基锂或丁基锂与二乙胺,哌嗪,N,N'-二苄基乙二胺,N-苄基哌嗪或1,3,3-三甲基-6-氮杂双环[3.2.1]辛烷制备的酰胺化锂可有效生成羧酸烯二醇锂即使是催化量。
