To further broaden the methods for the heterogeneous phase alkylation of CH acidic compounds, the dialkylation of diethyl ethoxycarbonylmethylphosphonate was studied in the presence of Cs2CO3 under microwave and solvent-free conditions. It was found that after repeating the alkylations by the addition of newer portions of the alkylating agent and the base on a few occasions, the dialkylation was quite efficient. Even dialkyl derivatives with different alkyl groups could be synthesized. The presence of a phase-transfer catalyst was harmful, as prevented the formation of the dialkyl products.
