Sustainable “green” Chemistry

Introduction

What is the role of photochemical reactions in green chemistry?

Photochemical reactions can often serve as excellent choices for green syntheses. One reason for this is that a photon, unlike chemical catalysts or reagents, leaves behind no waste or excess atoms. Photochemically initiated reactions can often proceed rapidly at ambient temperatures, since photoexcitation can be used to generate highly reactive species. In some cases, photochemical syntheses can also reach the synthetic target in fewer steps than those which rely on thermally initiated reactions.
