Metal‐Organic Framework Supported Copper Photoredox Catalysts for Iminyl Radical‐Mediated Reactions

Visible-light copper photocatalysis has recently emerged as a viable technology for building sustainable synthetic processes. To broaden the applications of phosphine-ligated copper(I) complexes, we describe herein an effective metal-organic framework (MOF)-supported photocatalyst multiple iminyl radical-mediated reactions. Due to site isolation, heterogenized photosensitizer significantly higher catalytic activity than its homogeneous counterpart. Using hydroxamic acid linker immobilize species on MOF supports affords heterogeneous catalysts with high recyclability. The post-synthetic modification sequence surfaces allows preparation previously unavailable monomeric species. Our findings highlight potential using MOF-based systems address fundamental challenges in development methodologies and mechanistic investigations transition-metal photoredox catalysis.
