Dibromoethane chemical ionization mass spectra of ten pairs of methyl (aand (a-cinnamates were studied. C,H4Br+ ion forms stable adducts with E-isomers and the adducts of Z-isomers show preferential loss of methanol. The observed results suggest that the probability of ring alkylation is greater th
