title: Sunlight induced functionalisation of some heterocyclic bases in the presence of polycrystalline TiO2.
abstract: The functionalisation of various heterocyclic bases induced by sunlight is reported. The photoreaction occurred with higher yield in a liquid-solid heterogeneous system in the presence of polycrystalline TiO2 (anatase) than in a homogeneous system under the same experimental conditions.
