Catalytic Oxidative Cleavage of C(OH)-C Bonds in Lignin Model Compounds to Carboxylic Acids by Fe(NO₃)₃.9H₂O/NaI/DMSO.

ABSTRACT: The secondary C(OH)-C bonds are abundant in biomass such as lignin and cellulose. Thus, selective cleavage of the C(OH)-C bonds into value chemicals attracted much attention. Molecular iodine has received considerable attention as an inexpensive and readily available catalyst to yield the corresponding products in excellent yields with high selectivity, but it is highly corrosive and toxic, making its use somewhat unattractive. In this study, I₂ was generated in situ from Fe(NO₃)₃.9H₂O/NaI, which was further combined with Fe(NO₃)₃.9H₂O to catalyze the oxidation process. In the reaction, the H₂O molecule from the reaction and Fe(NO₃)₃.9H₂O attacked the phenylglyoxa
