摘要：

Mass spectra of a series of 2-mono- and 1,2-disubstituted-1,4,5,6-tetrahydropyrimidines 1 and their methiodides 2 under electron impact (EI) are analyzed. A typical fragmentation pattern was found for each series of compounds. One of the fragmentation routes proposed for compounds 1 was confirmed by high resolution techniques. A fast atom bombardment (FAB(+)) technique was employed in order to detect methiodides 2 molecular ion. The chemical ionization (CI) spectrum of compound 2d is also analyzed.
