摘要

A process of reacting a ring carbon atom of an aromatic compound Ar with a compound of the formula H.sub.2 NCH&boxH;NH.sub.2.sup.+ CH.sub.3 CO. sub.2.sup.-, and an anhydride which has the ##STR1## at from 10° to 200° C. and preferably 25° to 40° C. to form a compound of the formula ##STR2## where m is 1, 2 or 3, and A is H or F. In the case where m is 1 the compound ##STR3## can be hydrolyzed to ArCHO. Additionally, Fischers base can be reacted with formamidine acetate to form ##STR4##
