CO homologation and Isocyanide Activation by a Trisilyl Alane Radical Anion

Abstract

We report the divergent reactivities of a trisilyl-substituted alane and its radical anionic species towards isocyanides and carbon monoxide. While the neutral Al(III) species forms coordination complexes, Al(II) radical promotes cyanide formation. Notably, the radical anion mediates CO homologation to yield a C3 fragment, which provides new insight into main-group CO homologation.
