Abstract
The atom-economical reaction of carbon dioxide (CO) with epoxides possesses the potential to utilize captured CO₂ for synthesizing useful chemicals. Among a wide range of metal complexes employed for this transformation, iron (Fe) stands out because of its low cost, ready availability, and stability. In this work, a pyridine-based pincer PN³-Fe(II) complex was synthesized and used as an efficient catalyst for the CO₂ epoxide cycloaddition. More importantly, this complex enabled the direct capture of CO₂ in the atmosphere and conversion into cyclic carbonates in excellent yields.
