Helfried Neumann; Stefan Klaus; Markus Klawonn; Dirk Strübing; Sandra Hübner; Dirk Gördes; Axel Jacobi von Wangelin; Michael Lalk; Matthias Beller

Abstract A new general synthesis of substituted luminols (5-amino-2,3-dihydrophthalazine-1,4-diones) is presented. Diversely substituted luminol derivatives can be synthesized in three steps. The products are of interest as new materials, which exhibit chemiluminescence.
