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.
