Base‐Free Monomeric Organogallium Hydrides

Abstract

Stable tricoordinate mono- and dihydrides of gallium, 1 and [(Ar)Ga(H)2], respectively, can be isolated by taking advantage of the kinetic stabilization afforded by bulky Ar substituents. The monohydride 1, prepared from [(Ar)2GaCl] and Li-GaH4, is the product of an unusual rearrangement reaction. Ar = 2,4,6-tBuC6H2.
