✦ Synopsis

The possibility of homo-aromaticity' existing in molecules with three properly disposed double bonds, such as cis,cis,cis-1,4,7-cyclononatriene (l)3 and triquinacene (,2)4 --has prompted a great deal of work with these systems.

In the case of the cyclononatriene 1 it was not possible by x-ray crystallography, nmr spectroscopy, or heats of hydrogenation to detect any interaction of the double bonds in 1.3 Recently, however, Heilbronner and coworkers, using photoelectron spectroscopy, have been able to show that there is a significant interaction of the TI bonds in t. 5
