Treatment of 1- and 4-aza- as well as 1,5-, 1,8-, 2,5-, and 4,5-diazafluorenones with hydrazine hydrate at 160-170 °C led to azafluorenes in the yield 33 - 90%. In the case of 4-aza-, 2,5- and 4,5-diazafluorenone, the dimerization products, 9,9’-bisazafluorenes were also formed under reduction conditions.
