Isolable Three‐Coordinate Base‐Stabilized Alumylene: A Precursor of Persistent Acceptor‐Free Monomeric Aluminum Oxide
Abstract
AbstractAn isolable monomeric alumylene 2 stabilized by two donating ligands (phosphine and NHC) has been synthesized. Experimental and theoretical analysis confirm that the NHC ligand in 2 is labile and reversibly dissociates from the AlI center above −20 °C. Of particular interest, despite being thermodynamically stabilized by two donor ligands, alumylene complex 2 exhibits a high reactivity with a considerably higher nucleophilicity compared to the monophosphine‐ligated complex 5. It is interesting to note that 2 reacts immediately with N2O at −90 °C, allowing the synthesis of bis‐ligated aluminum oxide 15, which is stable up to −70 °C.
