Oxidation of p-methoxyphenols and 6-chromanols by copper(r1) acetate in acetic acid gave the corresponding o-acetoxyphenols and 5-acetoxy-6-chromanoIs, which were easily hydrolysed in MeOH-H20 containing HCI to give catech o I -type p he no Is. ... In recent years increasing interest has been shown in the chemistry of the oxidation of phenols using copper(I1)- mediated oxidation processes1 and copper(r1)-based oxidation systems.2 o- Acetoxyphenols are ...
