Abstract
Treatment of alkylenebisbromomalonates with nucleophiles (AcOK, AgOH, KHCO3, 1,8-diazabicyclo[5.4.0]undec-7-ene, or Ph(3)P) results mainly i n their debromination to give cycloalkane-1,1,2,2-tetracarboxylates. W hen H2O and acids are present, the reaction gives products of the subs titution of one or two bromine atoms by hydrogen. Alkaline hydrolysis results in loalkane-alpha,alpha,alpha',alpha'-tetracarboxylic acids. T he reaction mechanism is discussed.
