Novel and efficient oxidation of benzyl ethers to benzaldehydes by DMSO/49% aqueous HB [PDF]
, 2007 Dimethylsulfoxide (DMSO) oxidizes benzyl ethers into corresponding benzaldehydes at 110°; the reaction is accelerated by 49% aq. HBr. The conditions work well for different aryl-substituted benzyl ethers.

Effect of pH on the Transient Reduction of Pig-Plasma Benzylamine Oxidase by Benzylamine Derivatives [PDF]
European Journal of Biochemistry, 1976 1. The transient kinetics of reduction of the 470-nm absorption band in benzylamine oxidase by substrate at different pH values between 6 and 10 have been studied by stopped-flow techniques, and substituent effects on kinetic parameters for the reduction process have been examined using a series of ring-substituted benzylamine derivatives as the ...
