Abstract
A easy and environmentally friendly method for the photochemical functionalisation of the heterocyclic bases is described. The selective introduction of the amido group of formamide, using sunlight and air in the presence of TiO2, has allowed to obtain the desired products in mild conditions with high conversions. The comparison of these results with those previously reported, in the presence of H2O2 instead of air, clarifies some aspects of the reaction mechanism.
