Electron impact mass spectra of some anthracene,anthrafuran and nitroanthrafuran derivatives. A tandem mass spectrometric collisional activation dissociation study

The 70-eV electron impact mass spectra of a series of thirty anthracene, seven anthra[2,1-b]furan and seven 2-nitroanthra[2,1-b]furan derivatives are described and discussed. A collisional activation dissociation study of 1-formyl-2,6-dimethoxy-9-methyianthracene, 1-formyl-2,6-dimethoxy-10-methylanthracene, and 2-carboxy-11-methylanthra[2,1-b]furan has been carried out using tandem mass spectrometry in order to substantiate the fragmentation schemes.
