Organometallo-macrocycle assembled through dialumane-mediated C–H activation of pyridines†
Abstract
Dialumane 1 reacts with pyridines at elevated temperatures through regioselective reductive dehydrogenation of 4-H, affording a unique hexanuclear Al(III) macrocycle [{LAl(pyridyl)}6], which represents the first dialumane-mediated C–H activation of Py and may suggest a new approach toward organometallo supra-molecules by one-pot small molecule activation and self-assembly.
