The electron impact mass spectra of new compounds, 2,4-dialkyl and 2,4-diaryl substituted-5,6-dihydrocyclobuta[d]pyrimidines, are reported. The main fragmentation pathway leads to the formation of cyclobutadiene [C 4 H 4 ] Á m/z = 52 as the base peak. The FAB spectra of the adducts of cyclobutapyrim
