Efficient Solvent-free Synthesis of Chloropropene Carbonate from the Coupling Reaction of CO2 and Epichlorohydrin Catalyzed by Magnesium Porphyrins as Chlorophyll-like Catalysts
Highly efficient solvent-free coupling reaction of carbon dioxide(CO
2
)and epichlorohydrin catalyzed by meso-tetraphenyl porphyrin magnesium(MgTPP)in the presence of triethylamine as co-catalysts is reported.As a chlorophyll-like catalyst
MgTPP showed excellent activity for the coupling reaction of CO
2
and epichlorohydrin to chloropropene carbonate
in which the turnover number could reach up to 9200.Moreover
different factors including the amount of catalyst
reaction temperature
pressure and time were systematically investigated and the optimal reaction conditions were obtained(epichlorohydrin 50 mmol
MgTPP 5.0×10
-3
mmol
triethylamine 6.25×10
-3
mmol
140℃
1.5 MPa
8 h).A plausible two-pathway mechanism for the coupling reaction of CO
2
and epichlorohydrin is proposed to propound the catalysis of MgTPP.
