Salen-Co(iii) insertion in multivariate cationic metal-organic frameworks for the enhanced cycloaddition reaction of carbon dioxide.

Abstract

The salen-Co(iii) motif was inserted into imidazolium-functionalized multivariate cationic zirconium metal-organic frameworks (MOFs). The salen-Co(iii), as a Lewis acid site, and the Br- of imidazolium, as a nucleophile, are synergistically catalytic for the enhanced cycloaddition reaction of carbon dioxide with epoxides.
