N-(2-Methoxycarbonyl-2-yloethyl)phenylaminyl: EPR observation of a triplet nonconjugated 1,3-diradical with two different kinds of radical centers
Abstract
EPR observation of N-(2-methoxycarbonyl-2-yloethyl)phenylaminyl at cryogenic temperature shows that the diradical has a triplet ground state, and is thermally labile for ring-closure reaction with low and distributive activation energies centered around 3.2 kJ mol−1.
