英文摘要: Several Fe(II) complexes were prepared as catalysts for the synthesis of oxazolidinones from terminal epoxides, aryl amines, and carbon dioxide. DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) was identified as a highly active co-catalyst for the formation of oxazolidinones. Mechanistic studies reveal that Fe(II) complexes act as reservoirs of the two active species including Lewis acid and carbene. The epoxides were activated via a Fe-O σ-bond between the Fe atom of the Lewis acid and the oxygen atom of the epoxide. Simultaneously, a nucleophilic carbene activates CO2 to form a carbene-CO2 adduct. In addition, interactions between the Lewis acid and epoxides accelerate the reaction of epoxides with aryl amines. DBU plays a crucial role in the reaction between the β-amino alcohol and cyclic carbonate. Under mild reaction conditions, various epoxides and aryl amines were converted to the corresponding oxazolidinones with good yields in the presence of CO2. © 2018 Elsevier Ltd. All rights reserved.
