title: Pd/C-catalyzed aerobic oxidative esteriﬁcation of alcohols and aldehydes: a highly efficient microwave-assisted green protocol.
abstract: We herein describe an environmentally friendly microwave-assisted oxidative esteriﬁcation of alcohols and aldehydes in the presence of molecular oxygen and a heterogeneous catalysis (Pd/C, 5 mol %). This efficient and ligandless conversion procedure does not require the addition of an organic hydrogen acceptor. The reaction rate is strongly enhanced by mild dielectric heating. Furthermore, it is a versatile green procedure which generally enables the isolation of esters to be carried out by simple filtration in almost quantitative yields.
