Synthesis of aromatic heterocycles by Palladium(0) catalyzed domino reactions and cyclization of hydrazone dianions This dissertation focuses on the development of new and convenient synthetic approaches for important or new aromatic heterocycles namely chromeno[3 4 b]pyrrol 4(3H) ones indolo[1 2 f]phenanthridines azaindolo[1 2 f]phenanthridines naphtho fused heterocycles and fluorinated pyrazoles which are potential for drug discovery and advanced materials. The approaches base on palladium(0) catalyzed domino reactions and cyclization of hydrazone dianions.<ger>
