A mixed basic metal sulfide catalyst having the formula: xA.yB.zC.qS wherein A is an alkali metal selected from lithium, sodium, potassium, rubidium, cesium and mixtures thereof; B is a cation which has an ionization state 1 greater than the ionization state of C; B is selected from scandium, yttriu

A mixed basic metal sulfide catalyst having the formula: xA.yB.zC.qS wherein A is an alkali metal selected from lithium, sodium, potassium, rubidium, cesium and mixtures thereof; B is a cation which has an ionization state 1 greater than the ionization state of C; B is selected from scandium, yttrium, lanthanum, actinium, aluminum, boron and mixtures thereof when C is selected from beryllium, magnesium, calcium, strontium, barium, radium, zinc, cadmium, mercury and mixtures thereof and B is selected from titanium, zirconium, hafnium, silicon and mixtures thereof when C is selected from scandium, yttrium, lanthanum, actinium, aluminum, boron and mixtures thereof; x and y are in mole fractions of z such that when z=1 then x=0.001 to 0.25, and y=0.001 to 0.25; and q is a number necessary to maintain charge balance with S being sulfur. The catalyst is useful for oxidative coupling of methane and aliphatic and alicyclic hydrocarbon compounds with an aromatic compound to produce higher molecular weight hydrocarbons; and for dehydrogenating hydrocarbon compounds to produce unsaturated aliphatic and alicyclic chains.
