ESR Spectroscopic Studies of Donor-Acceptor-Substituted Carbon Radicals

The radicals 2, 3a, 4, and 12 as well as 3b, and 17 were generated for ESR spectroscopic studies either by hydrogen abstraction with aminyl radicals or by oxidation with lead dioxide.Hydrogen abstraction from 5 did not give 6 but a secondary radical 7.Radical 16 was formed by reduction of the corresponding pyridinium iodide by zinc, whereas reduction of 13, and 8 afforded the radicals 15, and 11, respectively.The analysis of the ESR spectra allowed the determination of the spin density at various positions of these radicals.Furthermore, theoretical calculations of spin density - performed also for the radicals 1a and b, 21 and 22 - revealed the spin density distribution within the amino(cyano)alkyl group and the effects of further substituents on this.
