The mass apeotra of eleven fluorinated phosphonium glides have been analyzed.The following results have been observed: (1) The cleavage mechanism of EI mass spectra of fluorinated phosphonium glides was similar to that of phosphonium ylides forming a series of skeletal rearrangement ions,but CI mass spectra gave only the (C6H5) 2 ions.(2) For compounds 7 to 11 the characteristic alkyne ions were observed in all mass spectra.(3) For CI positive ion mass spectra,the oxygen rearrangement ion (m/z279) was observed.For compounds 1 to 11,all the base peaks were (M + H)+.(4) For CI negative ion mass spectra,the stable ion(M-·C6H5)-was formed.
