Enzymatic oxidation of lignin and compounds modeling it. V. Products of peroxidase oxidation of α-guaiacylpropanone

Using -guaiacylpropanone as an example, it has been shown that, in the process of peroxidase oxidation of carbonyl-containing structures, biphenyl compounds having C-C bonds in the 5-5 positions are formed. On the basis of the results of physicochemical methods of analysis, the formation of biphenyl spatially hindered structures with screened radical centers is suggested.Siberian Scientific-Research Institute of Cellulose and Cardboard, Bratsk.
