Authors: Johannes S. Schneider, Holger Helten
Abstract: Rare examples of three-coordinate aluminum cations of the form [(NHC)⋅AlMes2]+[B(C6F5)4]− and their etherate analogues [(NHC) ⋅ AlMes2(OEt2)]+[B(C6F5)4]−are presented. The Lewis-acidity of the cations was evaluated theoretically and experimentally to be very high. These cationic Lewis-acids form a frustrated Lewis-pair (FLP) upon addition of the phosphine PCy3, which reacts with small molecules such as CO2, ethene, and 2-butyne.
