Abstract
The iodomethylate of 9-chloro-4-azafluorene is converted to 1H-1-methyl-indeno[1,2-b]pyridine when treated with base. We discuss the structure of compounds containing azalene fragments, which are formed upon heating 9-chloro-4-azafluorene. We discuss some considerations concerning the nomenclature of azulenes with the azafluorene skeleton.
