## Abstract The electron impact (EI) induced mass spectral fragmentation of seventeen, including seven newly synthesized, Nโ1 and Cโ6 carboxyalkylโ and alkoxycarbonylalkylโsubstituted derivatives of uracil and thymine was investigated. Fragmentation pathways are proposed on the basis of accurate ma
The 75 eV electron impact mass spectra of 1,l-bis(dimethoxypheny1)methanes bearing u-methoxy groups are dominated by intense peaks corresponding, at least formally, to benzyl ions [ (CH,0)IC6H,CH, I + ( 6 ) . They arise from ions [ ((CH,O),C,H,),CHI + (u), which are in turn formed from molecular ion
