In situ Reaction Monitoring in Photocatalytic Organic Synthesis

Visible-light photocatalysis provides numerous useful methodologies for synthetic organic chemistry. However, the mechanisms of these reactions are often not fully understood. Common mechanistic experiments mainly aim to characterize excited state properties photocatalysts and their interaction with other species. Recently, in situ reaction monitoring using dedicated techniques was shown be well-suited identification intermediates obtain kinetic insights, thereby providing more holistic pictures interest. This minireview surveys technologies discusses selected examples where used elucidate mechanism photocatalytic reactions.
