- Abstract
- An imidazolium-cobaltate-based heterogeneous catalyst exhibits advantages over its homogeneous counterpart in the synthesis of -hydroxyesters from epoxides. However, leaching of cobaltate from the catalytic support decreases the selectivity and recyclability of the catalyst. To overcome such drawbacks, a bis-imidazolium-based covalent triazine framework (CTF) is employed as a catalytic support for the hydroesterification catalyst to reduce cobaltate leaching by the intramolecular anion stabilization effect of the multi-imidazolium moiety, resulting in an excellent selectivity for the -hydroxyester and unprecedented recyclability.
