Selective C–O bond cleavage at benzylic positions enabled by Zirconocene and Photoredox catalysis
We have developed a catalytic protocol for the selective cleavage of C–O bonds at benzylic positions using zirconocene and photoredox catalysis. This catalytic system enables the reductive cleavage of C–O bonds in both benzyl ethers and benzyl alcohols. Additionally, aromatic carbonyl compounds undergo deoxygenation to afford the corresponding hydrogenated products. Mechanistic studies support that ZrIII is the catalytically active species responsible for the C–O bond cleavage, driven by the formation of a strong Zr–O bond.
