Abstract: SUBSTITUTED AROMATIC COMPOUNDS CONTAINING THE SAME NUMBER OF CARBON ATOMS AS THE STARTING MATERIAL ARE PREPARED IN A TWO-STEP PROCESS BY SUBJECTING A GEMINALLY SUBSTITUTED CYCLOLKANE TO ISOMERIZATION IN THE PRESENCE OF A GOLD-CONTAINING CATALYST AT A TEMPERATURE IN THE RANGE OF FROM ABOUT 250* TO ABOUT 400*C. AND THEREAFTER AROMATIZING THE RESULTANT NON-GEMINALLY SUBSTITUTED CYCLOALKANE AT AN ELEVATED TEMPERATURE AND PRESSURE IN THE PRESENCE OF CERTAIN CATALYSTS TO PREPARE THE DESIRED PRODUCT. THE PROCESS IS EXEMPLIFIED BY THE CONVERSION OF 1,1-DIMETHYLCYCLOHEXANE TO ETHYLBENZENE AND O-XYLENE.
