## Abstract The mass spectral fragmentation of twelve new 2βalkoxycarbonylalkylthio substituted derivatives of uracils is discussed and fragmentation pathways, elucidation of which were assisted by accurate mass measurements and metastable transitions are proposed. It has been found that the basic

## Abstract The mass spectral fragmentations of sixteen new 2βand 4β__o__β(__m__β and __p__β)substituted benzylthiouracils and __o__β(__m__β and __p__β)substituted 2,4βdibenzylthiouracils with NO~2~ and CI substituents in the benzyl groups were investigated. Fragmentation pathways are proposed on t
The mass spectral fragmentations of eight 2-alkylthiouracils with C,,,, C I 2 , C,, and C,, in the alkylthio group were investigated. Fragmentation pathways are proposed on the basis of accurate mass and metastable transition measurements. The correlation between the intensities of the M" and [ M -'
