摘要：

Metalation of acetic, butanoic, or 2-methylpropanoic acid with lithium diisopropylamide in tetrahydrofuran under argon gave the corresponding lithium acylate -carbanions which reacted with carbon tetrachloride at 20-25 degrees C for 2 h to afford butanedioic acid or its 2,3-diethyl and 2,2,3,3-tetramethyl derivatives, as well as the corresponding -chlorocarboxylic acids and chloroform. A radical mechanism was proposed for the formation of dicarboxylic and -chlorocarboxylic acids.
