Abstract Four new heteroaromatic pentalenes have been synthetised by reductive cyclisation with triethylphosphite of the appropriate nitropyridylbenzotriazoles or nitrophenyltriazolo [4, 5-b] pyridines: the [2, 3-b] pyridino [4, 5] benzo-1, 3a, 6, 6a- tetraazapentalene 2;[3, 2-c] pyridino [4, 5] benzo-1, 3a, 6, 6a-tetraazapentalene 3;[3, 2-b] and [2, 3-b] pyridino [5, 6] benzo-1, 3a, 4, 6a-tetraazapentalene 5, 6. The spectral ...
