Reactions of alkylenebisbromomalonates with nucleophiles
摘要:
Treatment of alkylenebisbromomalonates with nucleophiles (AcOK, AgOH, KHCO3, 1,8-diazabicyclo[5.4.0]undec-7-ene, or Ph(3)P) results mainly in their debromination to give cycloalkane-1,1,2,2-tetracarboxylates. When H2O and acids are present, the reaction gives products of the substitution of one or two bromine atoms by hydrogen. Alkaline hydrolysis results in oxacycloalkane-alpha,alpha,alpha',alpha'-tetracarboxylic acids. The reaction mechanism is discussed.
Octasodium-1,1,2,2,4,4,5,5-cyclohexane octacarboxylate and compositions
