  Radical Cations of Trialkylamines:  ESR Spectra and Structures

  摘要：

  Novel syntheses of cyclopropyldiisopropylamine (15), di-tert-butylcyclopropylamine (16), dicyclopropylisopropylamine (17), and tricyclopropylamine (18) are described. Hyperfine data were determined by ESR spectroscopy for the radical cations of these trialkylamines, as well as for those of ethyldiisopropylamine (10), diisopropyl-n-propylamine (11), dicyclohexylethylamine (12), diisopropyl-3-pentylamine (14), and 1-azabicyclo[3.3.3]undecane (manxine; 27). The radical cation of triisopropylamine (13) was reexamined under conditions of improved spectral resolution. Coupling constants of the N-14 nucleus and the beta-protons in the radical cations of 18 trialkylamines provide reliable information about the geometries of these species, which are confirmed by theoretical calculations. With the exception of a few oligocyclic amines, for which flattening is impaired by the rigid molecular framework, all of the radical cations should be planar. Correlation between the observed coupling constants of the beta-protons and the calculated values of the dihedral angle theta, defining the conformation of the alkyl substituent or the azacycloalkane, is verified. Upon oxidation, striking changes occur for those amines that have cyclopropyl substituents, because of the tendency of these groups to assume a perpendicular conformation in the neutral amines and a bisected orientation in the corresponding radical cations.
