Cleavage within: The selective cleavage of β-O-4 bond linkage in lignin has received great attention. We developed a method using the commercially available heterogeneous catalyst, Pd/C, to cleave the C[BOND]O bond in β-O-4 linkage model compound without hydrogen. A mechanistic study shows that the present catalytic system undergoes a process different from previous reports, in which the β-benzylic-H atom in the substrates plays a critical role.
