Heats of Formation and Ionization Potentials of Some α-Aminoalkyl Radicals


Heats of formation and ionization potentials of α-aminoalkyl radicals, R2NCR'2, were derived from measurements of the appearance energies for the fragmentations of a series of ethylenediamines. Stabilization energies, Es, are high and increase with increasing C- or N-alkylation; the converse applies to ionization potentials, IP. For example, in the case of H2NC(Me)2, Es= 17 kcal mol-1 and IP = 5.4 eV. © 1983, American Chemical Society. All rights reserved.
