Conformational equilibria of 2,5-bis1-(phenylimino)ethylpyrazine anion radical (bpip·-). An electron paramagnetic resonance/electron-nuclear double resonance study of bpip·-, (bpip·-)(RMg+)2, and of the related anion radical of N-tert-butylpyridine-2-carbaldimine (But-pyca)

Abstract
EPR and ENDOR spectra were obtained for the title anion radicals (I and II). The spin distribution of both species reflects the mixed imine/azine compn. of the a-diimine chelate moieties. In the absence of coordinating electrophiles, bpip·- (I) displays ENDOR-detectable conformational equil., presumably between s-cis/s-cis, s-cis/s-trans and s-trans/s-trans isomers. Bpip reacts with MgR2 (R = 2-tolyl) in an electron-transfer fashion to form an organomagnesium radical complex. on SciFinder(R)
