Abstract

Isoeugenol [2-methoxy-4-(prop-1-en-1-yl) phenol; compound 1] can be oxidized to vanillin (4-hydroxy-3-methoxybenzaldehyde, compound 2) by H2O2 in the presence of the n- Bu4NVO3/pyrazine-2-carboxylic acid catalytic combination. A 50% yield of 2 was attained in a 2-h reaction at 80° C, with a turnover number being higher than 1200. Kinetics of the transformation of 1 into 2 have been studied. The results obtained indicate that the first ...
