MTO catalyzed oxidation of aldehyde N,N-dimethylhydrazones with hydrogen peroxide: high yield formation of nitriles and N-methylene-N-methyl N-oxide
Abstract
N,N-Dimethylhydrazones of aldehydes react with hydrogen peroxide at –50 °C in the presence of catalytic amounts of methyltrioxorhenium (MTO) to give in high yield the corresponding nitriles and N-methylene-N-methyl N-oxide.
