Organoaluminum Radical Complexes from the Single Electron Transfer Reaction of Diisobutylaluminum Hydride with N-Heterocycles

Abstract

Diisobutylaluminum hydride ⁱBu₂AlH reacts with N-heterocycles L (L = pyrazine, 2,2'-bipyridine, 4,4'-bipyridine) via single electron transfer to yield 1:1 radical complexes [L(AlⁱBU₂)·].
