Visible-light photoredox catalysis has witnessed a dramatic development over the past decade because it offers a promising synthetic technology which enables previously inaccessible transformations. Visible light is considered as a clean energy because of its high abundance, greenness, benign environmental impact, and sustainability. We have developed a visible-light induced photoredox catalysis for an efficient functionalization of benzylic C-H bonds with peroxides and halides. It was found that Blue and Green LED light can be utilized as the energy source to facilitate the formation benzylic radicals in the presence of a photocatalyst under mild reaction conditions. A series of benzylic hydrogen peroxides and halides bearing a variety of functional groups were prepared in good yields and regioselectivity.  <br/>
