Metal‐Organic Framework Catalyzed Hydrogen Atom Transfer for Photocatalytic Organic Synthetic Applications

ChemCatChem, Journal Year: 2024, Volume and Issue: 16(14)

Published: Feb. 26, 2024

Abstract This concept paper aims to summarize recent research on the design and synthetic applications of metal‐organic frameworks (MOFs)‐based hydrogen atom transfer (HAT) catalysts. Functional MOFs have emerged as highly promising heterogeneous catalysts, leveraging their tunable, ordered structure abundant active sites enhance catalytic efficiency in various reactions. HAT, a versatile method for generating open‐shell radical species through selective abstraction, has been well explored homogeneous photocatalysis. In contrast, HAT catalysis remains less developed, albeit great potential industry. will provide timely overview advancements MOFs‐based photocatalysis, classified according centers including aromatic ketones, polyoxometalates, xanthene dyes, thiols, alcohols, highlighting principles practical photocatalytic organic synthesis.

Cu‐catalyzed Formal Addition of Aliphatic C(sp3)–H Bonds to Alkenes via Phenyl Radical Involved Intermolecular HAT

Advanced Synthesis & Catalysis, Journal Year: 2024, Volume and Issue: 366(19), P. 4042 - 4048

Published: July 19, 2024

Abstract A copper catalyzed aerobic formal addition of aliphatic C( sp 3)−H bonds to alkenes via a phenyl radical mediated intermolecular HAT process is reported herein, in which the phenylhydrazine not only acts as reagent precursor, but also hydrogen atom donor. This reaction affords an alternative method for direct utilizing air initiator without additional reductants at ambient temperature. variety alkanes and electron‐deficient are successfully incorporated, furnishing series products 20–93% yield. Preliminary mechanistic studies show that 2‐tetrahydrofuranyl formed this reaction.
