Abstract: Inspired by the ability of natural photosynthetic systems to convert light energy into chemical        energy, the scientific community long ago recognized the potential of light mediated reactions      (photochemistry) as a very powerful approach to chemical synthesis. Over the last century, the discovery, development and use of photo-mediated catalysis have widened a novel field in organic synthesis. In the last decade, the field of photocatalysis has undergone a sensational mutation, and once again, a series of new activation modes enriched the broad chemistry of photocatalysis. This presentation focuses on how and why photocatalysis works and some very classical and latest works on this field.
