Abstract:
Abstract We report the efficient utilization of a transition metal complex based on an inexpensive and easy-to-handle 2,9-bis(imino)-1,10-phenanthronyl ligands as catalyst for the coupling of epoxides with carbon dioxide. This complex in the presence of tetrabutylamonium bromide produced a 77 % of carbonate conversion in the cycloaddition of CO2 and 1,2-epoxihexane at 30 bars, 80˚C in 20 h (0.1 mol % catalyst loading). The complex is stable under catalytic conditions and could be recycled by simple filtration maintaining the conversion in a second run.
