Abstract
Of three possible tricyclic regioisomers, the reaction of 1,2,4,5-tetrakis( bromomethyl)benzene with tosylated diethylenetriamine affords selectively a single product which has been assigned structure 4,7,10,15,18,21-hexakis(4 -methylbenzenesulfonyl)-4,7,10,15,18,21-hexaazatricyclo[11.9.1.1(2,12)]tetr acosa-1 (23),2(25), 12-triene with the aid of X-ray crystal analysis.
