synthesized by the addition of aryl Grignardcompounds to phthalodinitrile and subsequent reaction with formamide. A plausible reactionmechanism, through a Leuckart–Wallach‐type reduction has been confirmed by means of DFT calculations of the related transition and intermediate states. The corresponding boron difluoride complexes (10) of 9 were prepared in a subsequent reaction step and the spectroscopic and
