Influence of C g -OH on pyrolytic cleavage mechanism of b-ether-linkage in lignin dimer was studied in N 2 with C g -deoxy-type dimers, which have various p-substituents (-H, -Cl, -OCH 3 ) at their C b -phenoxy groups. Reactivities at 400 8C and the influence of radical scavenger (tetralin) indicate
