The conjugate aldehydes, containing terminal acetylenes, were converted to the corresponding conjugated azines 6a–c and 8a–c, respectively. Oxidative couplings of these azines were attempted. The azines 6b, 6c, and 8b afforded the corresponding cyclic dimers 9, 10, and 11, respectively. Examination of 1H NMR spectra indicates that the tetraazaannulenes are atropic.
