Our continuing interest in the syntheses and reactions of triazole derivatives (1) has led us to prepare the novel ring system, 1, 1'-dibenzyl-5, 5': 7, 7'-bis (hexano) bis [6 (1H)-cycloheptatriazolone] in order to study the effect of the polymethylene bridge on the aromaticity and planarity of a system which contains two triazoletropone systems within the same molecule (2, 3). The observed NMR chemical shift of 7.70 ppm from Me4Si of the protons H4 and H8 can be attributed to an increase in the planarity of the triazoletropone system and also to the existence of a ring current which leads to the conclusion that this compound is aromatic in the tropone ring portion.
