Methylene diesters were synthesized in high yields at room temperature by reacting the potassium salt of a carboxylic acid with dibromo methane under the conditions of solid-liquid phase transfer catalysis using poly (ethylene glycol)-600 (PEG-600) as the phase transfer catalyst.

Abstract A metal-free cross coupling between common CH2Cl2 and carboxylicacids has been achieved with K2CO3 as the sole additive. This simple protocol is a convenient and cost-effective route to synthesize methylene diesters from a wide scope of carboxylicacids substrates with good functional group tolerance. Several gram-scale reactions have been performed to evaluate the effectiveness and practicality
