Abstract

The regio-selective functionalization of a dialkyl benzene compound wherein the ratio of the compound functionalized at position (a) to the compound functionalized at the position (b) is at least 70:30, more particularly at least 80:20, still more particularly at least 85:15, and still more particularly at least 90:10, characterised in that the substituent R is an isobutyl group.
