Abstract

Procedure for the preparation of new aryl-1,3,5-triazines, of the formula ** (See formula) ** wherein R1 signifies a hydrogen atom, an alkenyl group containing up to 9 carbon atoms, an optionally substituted lower alkyl group, an aralkyl group or a radical of the formula -C0- (NH) n-1D1 wherein n is found for 1 to 2 and D1 is found for an alkyl, cycloalkyl or a phenyl group optionally substituted later, X1 means a group -OS- or -NH-, and A means an alkyl, alkenyl, cycloalkyl, aralkyl, phenyl or naphthyl containing up to 20 carbon atoms, which can in each case optionally carry other substituents, characterized in that in a trichlorogen chloride, with chlorine or bromine as halogens, a) the radical -X1-A is introduced by reaction with 2 moles of a compound H-X1-A, and b) the radical is introduced ** (See formula) ** wherein R1 has the above-indicated significance, by reaction with 1 mol of a corresponding 2,4-dihydroxy-benzene compound with at least one position is unsubstituted in the presence of Friedel-Crafts catalysts, in inert organic solvents, against the companions of reaction, free of water, and in which the succession of the introduction of these substituents can be any and eventually the hydroxyl group that is in position para to the triazine ring is etherified, esterified or transformed into urethane groups.
