Toluene dehydrocoupled products are produced by heating toluene in the vapor phase with an inorganic metal/oxygen composition which functions as an oxygen carrier and has the empirical formula: Ma1Mb2Ox where M1 is thallium and M2 is at least one element selected from arsenic, antimony, thorium, uranium, the lanthanides or rare earths, Groups 3b, 4b, 5b, and 7b of the Periodic Table of the Elements, and mixtures thereof, and wherein a is 1, b is 0.01 to 10, and x is a number taken to satisfy the average valences of M1 and M2 in the oxidation states in which they exist in the composition. Alternatively, the same inorganic metal/oxygen composition can be employed as a catalyst or as a combination catalyst/oxygen carrier for the dehydrocoupling reaction when oxygen or an oxygen-containing gas is heated with the toluene.
