It has been shown that the enzyme ligninase is able to catalyse the oxidation of a number of non-phenolicaromaticcompounds. The characterisation of two new products from 1,4-dimethoxybenzene and 1,2,3,5-tetramethoxybenzene is also reported. The ability of di-, tri- and tetramethoxybenzene derivatives to facilitate the oxidation of less readily oxidised substrates such as anisyl alcohol and 4-methoxymandelic

Upon UV-irradiation in methanol, bis(methoxyphenyl) methylphosphonates underwent an intramolecular coupling of two methoxyphenyl groups to give dimethoxybiphenyls and dimethoxy-9,10-dioxaanthracenes. The reactivities and fluorescence spectra of the phosphonates were sensitive to the position of the methoxy group. These photo-induced couplings proceed probably through the formation of the two types of singlet intramolecular excimers.
