Calix[4]pyrrolato gallate: square planar-coordinated gallium(<scp>iii</scp>) and its metal–ligand cooperative reactivity with CO<sub>2</sub> and alcohols
Lukas M. Sigmund, Eliane Engels, Nick Richert, Lutz Greb
Abstract
. While alcohols are found unreactive against the gallates, a rapid and selective OH-bond activation can be triggered upon protonation of the ligand. Secondary ligand-sphere modification adds a new avenue to structurally-constrained complexes that unites functional group tolerance with unconventional reactivity.
