Abstract

The formation and photo degradation of deferiprone chelate complexes with calcium and zinc ions have been studied by CIDNP and LFP methods. It was established that deferiprone in complexes undergoes rapid decomposition under the UV irradiation. Radical intermediates of deferiprone have been registered, and it was shown that the quantum yield of deferiprone photo degradation in the complex with zinc increases by 6.4 times.
