Abstract: Background: In this Chapter an overview on visible light photocatalyzed carbonheteroatom bond formations (C-N, C-O, C-P, C-S/Se/Te etc.) and the synthesis of related compounds by environment friendly approach has been reported. We have discussed visible light photocatalyzed C-N bond formation including amination, imination, azidation, and amidation. Construction of C-O and C-P bond have also been studied by photoredox catalysis under visible light irradiation implicating a novel, powerful and green strategy. Visible light photocatalysis is also useful in the formation of C-S/Se/Te bonds avoiding harsh reaction conditions.

Methods: Moreover, using visible light irradiation the synthesis of many important heterocycles such as N-containing heterocycles (pyridine, quinoline, phenanthridine, dibenzo[a,f]quinolizidine and pyrroles etc), O-containing heterocycles (benzocoumarin, tetrahydrofuran and tetrahydropyran ), P-containing heterocycles (benzo[b]phosphole oxide), N-O-containing heterocycles (oxazole, isoxazole benzoxazole etc), N-S-containing heterocycles (thiazole and benzothiazole) and OS- containing heterocycles (oxathiolane) have been demonstrated.

Conclusion: A series of representative reactions and examples have been provided and in specific cases reaction mechanisms have been discussed for better understanding of the reaction.
