The efficient syntheses of dialkyl cyclopropane- 1,1-dicarboxylates and alkyl 1-cyanocyclopropanecarboxylates; by alkylation of dialkyl malonates and alkyl cyaroacetates with 1,2-dihaloethanes are described. The importance of a certain amount of water under the solid-liquid phase-transfer conditions is demonstrated in the reactions.
