Popis:	The title compounds, 5,5′-diacetyl-2,2′,3,3′-tetramethoxy-1,1′-biphenyl, C20H22O6, and 5,5′-diacetyl-2,2′-diethoxy-3,3′-dimethoxy-1,1′-biphenyl, (IUPAC nomenclature), C22H26O6, correspond to the 5,5′-biphenyl-type lignin model compound. They were synthesized from dehydrodiacetovanillone by alquilation with CH3I and C2H5I. In the former compound, all non-H atoms in the asymmetric unit are planar except for one C atom. In the latter compound, there are two molecules of different conformations, one of which is affected by disorder.
