N,N′,N″-Triarylbenzene-1,3-5-tricarboximidoyl chlorides reacted with sodium azide under conditions of phase-transfer catalysis to give functionally substituted tetrazoles whose subsequent functionalization led to complex heterocyclic structures which may be regarded as first-generation tetrazole-containing dendrimers.
