Abstract: Mass Spectra of Quinoxzaline DerivativesZou Jianping;Lu Zhonge;Nakayama Mitsuru(Department of Chemistry,Suzhou University,Suzhou 215006,China)Received Abstract:The EI mass spectra of 2,6-and 2,3-disubstituted quinoxzaline derivatives are reported.Their mass spectral fragmentations are proposed on the basis of high resolution MS and the B/E linked scan mass spectra.Keywords:quinoxzline;EIMS;fragmentation
