Organometallic additions to quinone monoketals1t2 followed by acid hydrolysis provide an excellent route to p-quinols; however, reduction of the quinone monoketal by the organometallic reagent or rearrangement during the ketal hydrolysis serve as limitations on the method. For certain systems, the acidic conditions required for ketal hydrolysis result in fragmentation or rearrangement reactions to the virtual exclusion of p-quinol formation. ...
