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 die

Dichloromethane (DCM) as a C1 source has been discovered: methylene diesters from DCM and carboxylic acids or aldehydes with TBHP in water were efficiently synthesized. The reactions proceed under mild conditions and afford both aliphatic and aromatic met

Aldehyde acylals have been prepared and reacted with Grignard and alkyllithium reagents. Acylals from formaldehyde furnished complex reaction mixtures when reacted with both reagents. Acylals of other aldehydes gave reaction mixtures that consisted mainly of an ester, generated by replacing one of the carboxy groups with the organic part of the organometallic reagent, and regenerated aldehyde. The esters were formed in the highest yields. Yields above 90% were experienced when the acylals were reacted with Grignard reagents under Barbier conditions.

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
