A new, transition-metal-free, effective method for aromatic esterification of amides with organoboronic acids has been developed, leading to a wide range of benzoate derivatives with yields ranging from moderate to good. The catalytic reaction shows broad substrate scope and excellent functional group tolerance.

ABSTRACT A practical and chemoselective method for the synthesis of substituted phenyl benzoates using rare earth zeolite as catalyst was described, its recycle procedure offers high total yield.
A simple procedure affording benzoates through a NHC‐catalyzed aerobicoxidativeesterification of aldehydes with organoboronic acids has been disclosed. This process allows access to a wide variety of aromatic esters in good to excellent yields under simple, efficient, and sustainable reaction conditions (see scheme).
