The title compds. were prepd. by oxidative dimerization of C6H6 or PhMe at 70-110° and 5-20 atm partial O pressure in the presence of a catalyst consisting of an aq. HOAc soln. of Pd(II) phosphomolybdovanadate. The yield of title compds. was increased and the procedure simplified by using C8-C10 paraffinic hydrocarbon as the solvent at a vol. ratio to the initial raw material of 3.3-4.7:1 or by using C8-10 paraffinic hydrocarbon satd. with HOAc as the solvent.
