We did, of course, verify that a radical trap (TEMPO) does not influence the distribution of products under the standard reaction conditions (cf. Experimental Section)
-
19. This augurs well for a non-radical mechanism. It should, however, be noted that radical processes can be triggered by means other than heating or irradiation (for an example of a radical reaction catalyzed by oxygen, see : Barton, D. H. R., Bridon, D., Zard, S. Z. Tetrahedron Lett. 1986, 27, 4309-4312). We did, of course, verify that a radical trap (TEMPO) does not influence the distribution of products under the standard reaction conditions (cf. Experimental Section).
