Not so inert mer-tris-chelate cobalt(iii) complex of a hydroxy-pyridine functionalized NHC ligand for cyclic carbonate synthesis†‡
Abstract
The homoleptic hydroxy-pyridine functionalized Co(III)–NHC complex (2) demonstrates extraordinary catalytic activity towards the CO2 cycloaddition under mild conditions. Using this catalyst and TBAB, the highest TON (666 667) and TOF (52 713 h−1) were achieved compared to previously reported cobalt catalysts.
