Abstract

Ligand bite angle, a common parameter to fine-tune reactivity in transition-metal chemistry, is used for the first time in main-group chemistry to control and tune the Lewis acidity in organobismuth cations bearing 2-(dimethylamino)methyl]phenyl (Me2NCH2C6H4) and 2-(dimethylamino)phenyl (Me2NC6H4) ligands. The latter chelating ligand induces a shorter C-Bi-N bite angle, leading to a weaker Bi-N bond with a corresponding lower Bi-N sigma*-acceptor orbital and hence exhibiting remarkably higher Lewis acidity. The Gutmann-Beckett method is successfully employed to quantify the Lewis acidity in organobismuth cations.
