Abstract

Abstract The principal ions in the electron impact mass spectra of a series of 6- methoxyaurones have been shown to be due to four separate reactions associated with proximity effects involving the phenyl group and the coumaran-one residue. A detailed study with labelled derivatives has been supplemented by a study of the vinylogue 2- cinnamylidene-6-methoxycoumaran-3-one and compounds in which the aurone phenyl ...
