Abstract:
The present invention relates to unsymmetrical and symmetrical phosphorus-comprising heptazine derivatives, represented by the formula (1): in which Ra, Rb and Rc are, independently of one another, an azide group —N3 or an —N═PR1R2R3 group, with the proviso that at least one radical from Ra, Rb and Rc is an —N═PR1R2R3 group, to a process for the preparation thereof and to the use thereof.
