Dw. Brown et al., SOME SINGLE ELECTRON-TRANSFER REACTIONS OF ARYLIMINES, Journal of the Chemical Society. Perkin transactions. I, (16), 1997, pp. 2337-2343
When treated with suitable alkyllithiums, arylimines may undergo singl
e electron-transfer and conjugative substitution in the aryl ring, as
well as nucleophilic addition to the imine bond, Multiple substitution
s by tert-butyl radicals are noted, giving rise to rearranged and oxid
ized products, including cycloadducts.
