• Synthesis of esters from aldehydes or carboxylic acids with dichloromethane, dichloroethane or dichloropropane under mild conditions

  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 methylene diesters in good to excellent yields (up to >99%). 2-Chloroethyl benzoates and 3-chloropropyl benzoates are easily obtained in the same way from 1,2-dichloroethane and 1,3-dichloropropane, respectively, in good to excellent yields.

  二氯甲烷（DCM）作为C1来源的新发现：DCM与羧酸或醛在TBHP水溶液中高效合成了亚甲基双酯。这些反应在温和条件下进行，能够以优异至极佳的产率（高达>99%）得到脂肪族和芳香族亚甲基双酯。同样的方法，可以从1,2-二氯乙烷和1,3-二氯丙烷分别容易地获得良好的至极佳产率的2-氯乙基苯甲酸酯和3-氯丙基苯甲酸酯。

  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

  日期：——

  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.
