Addition of CO 2 to alkyl iron complexes, Fe(PP) 2 Me 2
The reactions of cis- and trans-Fe(dmpe)2Me2 (1) [dmpe = 1,2-bis(dimethylphosphino)ethane] and cis/trans- Fe(depe) 2Me2 (6) [depe = 1,2-bis(diethylphosphino)ethane] with carbon dioxide (CO2) were investigated along with the isomerization properties of the starting materials 1 and 6. Irradiation with UV light cleanly isomerizes the dimethyl complexes from their cis configurations 1a and 6a to their trans configurations 1b and 6b. At 300 K, addition of CO2 (1 atm) to 1 or 6 forms a stable methyl...[Show more]
