Abstract

original image

Alkyl aluminate/gallate exchange: Homoleptic barium tetraethylaluminate, synthesized from [(Ba{N(SiHMe2)2}2)n] and AlEt3 according to an extended silylamide elimination protocol, can be efficiently converted into the respective tetraethylgallate complex by diethyl ether assisted [AlEt4]/[GaEt4] exchange. Distinct Group 13 metal–alkyl bonding is featured in polymeric and toluene-coordinated dibarium solid-state structures.
