Access to diverse germylenes and a six-membered dialane with a flexible β-diketiminate

Abstract

A nacnac-based tridentate ligand containing a picolyl group (L) was employed to isolate chlorogermylene (1). The reaction of 1 with another equivalent of GeCl₂·dioxane surprisingly gave pyridylpyrrolide-based chlorogermylene (2) via C–N bond cleavage and C–C coupling, while with AlCl₃, it afforded a transmetalated product, 4. The reaction of L with AlH₃·NMe₂Et led to an unusual cyclohexane type six-membered dialane heterocycle (5).
