    Abstract: A process for producing an alkenyl substituted aromatic compound having the general formula (I): ##STR1## wherein Ar represents an aromatic ring, R.sup.1 represents an alkenyl group having 2 to 8 carbon atoms, p is 1, 2, or 3 provided that R.sup.1 may be the same or different when p is 2 or 3, R.sup.2 represents an alkyl group having 1 to 8 carbon atoms, q is 0, 1, or 2 provided that R.sup.2 may be the same or different when q is 2, X represents --OH or --NR.sup.3 R.sup.4 wherein R.sup.3 and R.sup.4 independently represent hydrogen or an alkyl group having 1 to 2 carbon atoms, n is 1 or 2, provided that the sum of p and q is 1, 2, or 3 comprising the step of catalytically dehydrogenating an alkyl substituted aromatic compound having the general formula (III): ##STR2## wherein R.sup.5 represents an alkyl group having 2 to 8 carbon atoms and Ar, R.sup.2, X, p, q, and n are the same as defined above, n is 1 or 2, provided that R.sup.5 may be the same or different when p is 2 or 3 in the presence of a catalyst comprising (a) at least one iron oxide as a main component and (b) at least one oxide of metals belonging to the group III, IV or V of the periodic table of atoms.This catalyst can produce an alkenyl substituted aromatic compound having a hydroxyl or amino group in the aromatic ring thereof from the dehydrogenation of the corresponding alkyl substituted aromatic compound at a high yield and high selectivity and has a prolonged catalyst life.
