O-Quinol diacetates

A number of o-quinol diacetates have been prepared and they rearrange smoothly to triacetoxyben-zenes o — o migration is preferred unless the latter position is blocked or sterically crowded, when acetoxy shift is directed to another aryl site. The range of possibilities is indicated by the conversions of the o-quinol diacetates (131)-(134) to the 1,2,3- or 1,2,4-triacetoxybenzenes (135)-(138), in 56-90% yields.
