Insertion into Other E-X Bonds

Recently, the reaction of insertion of CO2 into the aziridine ring has been investigated in SC-CO2 [175] and the formation of copolymers has been shown to occur under good control. 

CO2 may react with several E-X systems to afford insertion products. Here we wish to discuss some cases that may be relevant either to the synthesis of metal complexes that may have an application as catalysts or maybe relevant to synthetic applications.
