Selective cleavage of C_α–C_βbonds in lignin models using a bifunctional pyridinium photocatalyst<i>via</i>a PCET process

Abstract

A pyridinium-based photocatalyst possessing both redox-active and hydrogen acceptor sites has been developed for the conversion of lignin models to afford benzaldehyde and phenyl formate as the main products through selective cleavage of C–C bonds.
