## Abstract Reaction of 4,5‐diazafluoren‐9‐one (dafone, 6) and zinc dichloride yields [(dafone)ZnCl~2~(H~2~O)] (11) in which the ZnCl~2~ moiety is coordinated to a single nitrogen atom and also to a molecule of water. Hydrogen bonding, not only to the uncomplexed nitrogen atom of dafone but also to
## Abstract Some novel salts of 4,5‐diazafluoren‐9‐one N‐monosubstituted have been obtained by using Kröhnke method. The ability of 9‐oxo‐4,5‐diazafluorenium phenacylides (as 1,3‐dipoles) to react with activated symmetric dipolarophiles to give new heterocyclic compounds is presented. The new heter
