  Abstract A metal-free cross coupling between common CH2Cl2 and carboxylic acids 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 carboxylic acids substrates with good functional group tolerance. Several gram-scale reactions have been performed to evaluate the effectiveness and practicality

  An efficient methodology for the synthesis of symmetrical methylene diesters was developed through direct reaction of various aromatic carboxylates with 1,n-dihaloalkanes under solvent-free conditions. This strategy offers a high product yield, facile work-up and purification, and an environmentally friendly approach to obtain long-chain methylene carboxylate scaffolds with increased diversity.

  A convenient four-component reaction has been developed that allows for the direct transformation of aryl iodides with alkyl halides into the corresponding aromatic esters and diesters via palladium-catalyzed carbonylation with water as solvent. Various esters and diesters were isolated in moderate to good yields with broad functional group tolerance.

  A facile, rapid and solvent-free method for the conversion of acids and dihalomethane to the corresponding methylene diesters (acylals) using microwave as activators or assistor, is reported. This method is particularly powerful for the diesterification of carboxylic acids, which afford methylene diesters in good to excellent yields (up to >99%). When the intermediate is trapped, a "double successive S(N)2 reactions" mechanism is proved. (C) 2014 Bai-Wang Sun.
