Mass spectra of some 3-substituted benzo[b]quinuclidines III

The mass spectra of 3-methoxycarbonyl-, 3-ethoxycarbonyl-, 3-(2-dimethylaminoethoxy)carbonyl-, 3-amino-, 3-hydroxymethyl-, 3-chloro-3-methoxycarbonyl-, 3-chloro-3-ethoxycarbonyl-, and 3-chloro-3-cyano-substituted benzob]quinuclidines were investigated. The fragmentation of these compounds under electron impact through the open form of the molecular ion is discussed.See 1] for communication II.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 825–832, June, 1972.
