TL;DR:
The results showed that biphenyl (5-5) and stilbene structures of the residual lignin in the pulp are preferentially degraded in both the C1- and C2-catalyzed bleachings, whereas beta-O-4, beta-5, and beta-beta structures undergo degradation to a lesser extent.

Elucidation of the structures of residual and dissolved pine kraft lignins using an HMQC NMR technique
JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY, 51(21), 6116–6127.
author keywords: residual lignin; kraft lignin; kraft pulping; NMR; 2D HMQC technique; lignin-carbohydrate complex; condensation reactions; lignin degradation products
MeSH headings : Carbohydrate Conformation; Carbohydrates / analysis; Industry; Lignin / chemistry; Lignin / isolation & purification; Magnetic Resonance Spectroscopy / methods; Molecular Structure; Pinus / chemistry; Wood
TL;DR:
Elucidation of the role of condensation reactions indicates that an increase in the degree of lignin condensation during pulping results from accumulation of original condensed lign in moieties rather than from the formation of new alkyl-aryl structures.

Reaction mechanisms in delignification of pine Kraft-AQ pulp with hydrogen peroxide using Mn(IV)-Me4DTNE as catalyst
JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY, 51(7), 1932–1941.
author keywords: pine Kraft-AQ pulp; binucleus Mn(IV) complex; hydrogen peroxide bleaching; catalysis; residual lignins; alkaline soluble lignin; 2D HMQC NMR spectroscopic technique; epoxidation of conjugated double bonds
MeSH headings : Hydrogen Peroxide / chemistry; Lignin / analysis; Lignin / chemistry; Magnetic Resonance Spectroscopy; Organometallic Compounds / chemistry; Wood
TL;DR:
The results showed that biphenyl (5-5) and stilbene structures are preferentially degraded in the bleaching process, while beta-O-4, beta-5, and beta-beta structures undergo degradation only to a lesser extent, which implies that hydrogen peroxide bleaching using the catalyst is more effective in delignification of softwood pulps than hard wood pulps.
