✦ Synopsis

Lithium carboxylic acid enediolates are generated efficiently using lithium amides prepared from thienyllithium or butyllithium and either diethylamine, piperazine, N,N'-dibenzylethylenediarnine, N-benzylpiperazine or 1,3,3-trimethyl-6-azabicyclo[3.2.1 ]octane, even in catalytic amounts.
