Synthesis and Structural Comparisons of NHC-Alanes

N-heterocyclic carbenes (NHCs) are widely used in organometallic chemistry. Here, we examine the role of NHCs stabilisation aluminium hydrides, AlH3, also known as alanes. This includes an assessment various synthetic strategies, comparisons structural parameters and theoretical insight. Based on percent buried volume (%Vbur) parameters, report largest smallest NHC alanes to date, with noted differences their observed stability both solution solid state.
