  Proximity effects in the electron impact mass spectra of aurones and related compounds

  摘要：

  AbstractThe 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by a study of the vinylogue 2‐cinnamylidene‐6‐methoxycoumaran‐3‐one and compounds in which the aurone phenyl group has been replaced by α‐naphthyl, β‐naphthyl and 9‐anthryl.
