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
