Decay sequences - ionic series of mass spectra for 2,4,6-tris(perfluoroalkyl)-1,3,5-triazines

Abstract

: This report presents the ion series of mass spectra for eight homologues of 2,4,6-tris(perfluoroalkyl)-1,3,5-triazines from NIST libraries, including the ion series of two isomers: triazine (C 3 F 7 ) 3 C 3 N 3 with symmetrical substituents C 3 F 7 and triazine (CF 3 ) 2 C 3 N 3 (C 7 F 15 ) with unsymmetrical substituent C 7 F 15 . The influence of molecular weight of substituents and their symmetry on fragmentation of 1,3,5-triazines is discussed. Using [(CF 3 ) 3 CO] 3 C 3 N 3 homologue with oxaperfluoroalkyl substituents as an example, the effect of (CF 3 ) 3 C groups and oxygen atoms on fragmentation is discussed
