Abstract

Process for the preparation of new arylamides and aralkylamides of the general formula (I) ** (see formula) ** Wherein r is a univalent radical derived from an acyclic and aliphatic hydrocarbon having 2 to 19 carbon atoms or a univalent radical derived from a cyclic hydrocarbon and, when r is a univalent radical derived from an acyclic and aliphatic hydrocarbon having 2 to 19 carbon atoms: a) n is zero or one and x and y are hydroxyl; or b) n is two and x and y are independently hydrogen, fluorine, trifluoromethyl or hydroxyl, with the proviso that at least one of x and y is other than hydrogen and, when x is hydrogen, y is other than hydroxyl; and when r is a univalent radical derived from a cyclic hydrocarbon: a) n is zero and x and y are hydroxyl; or n) is one or two and x and y are independently hydrogen, fluorine, trifluoromethyl or hydroxyl, with the proviso that, when n is one, at least one of x and y is other than hydrogen, or c) with the proviso that that if r is adamantyl, n is zero, one or two and x and y are independently hydrogen, fluorine, trifluoromethyl or hydroxyl, with the proviso that when n is zero, x and/or y are (is) other than hydrogen, characterized by reacting a compound of the general formula (III) ** (see formula) ** Wherein x, y and n are as defined above and z is hydrogen or an acyl group -cor', wherein r' is different from the desired r group, with an acylating agent capable of introducing the desired -cor group, where r is as defined above.
