Popis:	The hydrogen-carbon, carbon-carbon double rearrangement, responsible for the formation of benzyl or tropylium ions previously observed in the electron ionization mass spectra of several substituted 1,1-bis(dimethoxydiphenyl)methanes bearing an ortho methoxy group, also occurs for 2-methoxydiphenylmethane (1) itself, the simplest compound of the series. It was shown using deuterium and 13 C labelled 2-methoxydiphenylmethanes (2, 3) that in this instance benzyl or tropilium ions are also formed through two alternative fragmentation routes
