Lignin is an attractive renewable carbon feedstock for the production of chemicals or fuels. �-Hydroxy aryl ethers are the most abundant functional group in Lignin's polymeric network and lignin derived crack products. Therefore, (2-phenoxy)phenylethanol compounds are widely used in model studies.In the present work Methyltrioxorhenium as precatalyst has been investigated and applied in the homogenous cleavage of Lignin model compounds. A quantitative conversion of the model compound to phenylacetaldehyde and guaiacol can be obtained in an almost equal ratio.
