Spin-polarized (CIDEP) neutral α-aminoalkyl radicals from tertiary amines observed in solution by flash-photolysis electron spin resonance

Abstract

Laser flash photolysis of benzene-1,2:4,5-tetracarboxylic dianhydride in the presence of tertiary amines yielded α-aminoalkyl radicals, many of which had not been observed previously in solution. They were produced in a spin-polarized state via the Triplet Mechanism, to facilitate their observation by e.s.r.
