Abstract 2-Amino-1-[(3-chloro-2-quinoxalinyl)azo]naphthalene was obtained by oxidative coupling of 3-chloro-2-hydrazinoquinoxaline with 2-aminonaphthalenesulfonic acid; cross self-cyclization of the product was used to synthesize macrocyclic compounds, viz., [1,2,5,8,9,12]hexaazacyclotetradecene derivatives. 4-[(3-Chloro-2-quinoxalinyl)azo]-5-chloro-3-methyl-1-phenylpyrazole was obtained by the reaction of the 4-(3-chloro-2-quinoxalinyl)hydrazone of 2,4-dihydro-5-methyl-2-phenyl-3H-pyrazole-3,4-dione with POCl3. Reaction of this product with 2,2′-diaminoazobenzene under standard conditions gave [1,2,5,8,9,12]-hexaazacyclotetradecene derivatives.
