Abstract
The dissociative ionization of 12 compounds of the 2- and 4-(2-furyl)pyridine series that contain methyl, ethyl, and n-propyl groups in various positions of the pyridine ring was investigated. It was established that the intensity of the [M — H]+ ion peak depends only slightly on the mutual orientation of the alkyl groups and the furyl grouping, while the probability of cleavage of the furan ring with ejection of CO and HCO particles is very sensitive to these structural factors. Cleavage of the pyridine ring leads to the development of [M — HCN]+ and [FuCN]+ ions.
