Several catalytic protocols for the oxidation of hydrosoluble substrates are presented that employ totally inorganic and robust polyoxometalate-based catalysts as well as porphyrin sensitizers, fullerenes and hybrid conjugates. Strategies for the implementation of the system stability and efficiency are discussed.

alloxanic radical, which ultimately serves as anodic co-reactant for [Ru(bpy)3]2+. The proposed new ECL oxidative-reduction mechanism via energetic electron transfer takes place between alloxanic radical and the electro-oxidized [Ru(bpy)3]3+. The developed an ECL based sensor which shows more sensitive and selective detection of alloxan with a linear ranges of 100 nM - 2 mM at pH 7.4 and 10 nM - 2 mM at

A series of hydurilic acid derivatives (5,5'-bipyrimidinyl-2,4,6,2',4',6'-hexaones) including several new derivatives was synthesized from 5,6-diaminouracils. Mechanisms for their formation are proposed and discussed. Furthermore, a new method for the preparation of pyrimidine-2,4,5,6-tetraone-5-oxime derivatives (violuric acids) was found starting from 5-amino-6-nitrosouracils.
