Metals in the synthesis of macrocycles. Part II. The structure of the macrocycles obtained from the interaction of 1,3,3-trichloroisoindolenine and 2,4-diamino-6-phenyltriazine

Abstract

The interaction of 1,3,3-trichloroisoindolenine, 2,4-diamino-6-phenyltriazine, and copper powder, in high-boiling solvents, gives a violet copper derivative of the macrocycle 5,17-dihydro-6,11:19,23-di-imino-5,25:13,17-dinitrilo-15,21-diphenyl-3H-dibenzo[o,s][1,3,5,7,9,11,13]hepta-azacycloheneicosine (cf. Ring Index no. 11469). Use of cupric chloride instead of copper powder gave a yellow-green, copper-containing derivative of the macrocycle 5,12-dihydro-13,18:20,24-di-imino-5,26:7,12-dinitrilo-22-phenyltribenzo[i,n,r][1,3,5,7,12]penta-azacycloeicosine.
