本文报道11个含氟膦叶立德的电子轰击(EI)质谱和化学电离(CI)正、负离子质谱。前者的断裂机理和一般膦叶立德相似,形成一系列骨架重排离子,而后者只出现(C6H5)2离子。在1～11的CI正离子质谱中,基峰均为[M+H]+,在7～11中还观察到氧重排离子m/β279。CI负离子质谱出现稳定的[M-·C6H5]-离子,化合物7～11的正、负离子质谱都出现特征的炔离子和炔基正离子。

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.
