Dehydrogenatable hydrocarbons are dehydrogenated by contacting them at dehydrogenation conditions in the presence of a complex oxide catalyst comprising molybdenum, copper and tin and at least one element selected from the group consisting of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, La, Ce, Th and U. For example, an alkyl aromatic hydrocarbon, e.g. ethylbenzene, can be dehydrogenated to an alkenyl aromatic hydrocarbon, e.g. styrene, in the presence of an oxide complex catalyst comprising molybdenum, copper, tin and at least one element selected from the group consisting of K, Cs, Ba, Mg and Ca.
