Introduction
Visible light photoredox catalysis has received much attention in recent years as a mild and sustainable activation mode for organic molecules. In particular, when coupled with microreactor technology, an efficient irradiation of the reaction medium is achieved. Interestingly, this offers new synthetic opportunities to organic chemists by bringing often avoided reagents into play. In his presentation, Timothy Noël gave an overview of the synthetic methodology development of his research group, exemplified by photoredox catalysis, and he showed how these synthetic methods were impacted by continuous-flow microreactor technology.
