The novel macrocyclic diamides , are obtained in 45–66% yields by the reaction of dipotassium salts and with each of 1,4-di(bromomethyl)benzene , 2,6-di(bromomethyl)naphthalene and 9,10-di(bromomethyl)anthracene , repectively, in boiling DMF. On the other hand, the new macrocyclic Schiff bases and are obtained in 44% and 42% yields by heating the appropriate bis-amines , with the corresponding bis-aldehydes
