The copolymerization of carbon dioxide and cyclohexene oxide is a promising route to activate and use CO2 as a renewable C-1 source. We report the synthesis, characterisation and catalytic studies in the copolymerisation using the new complex (Fig. 1). The catalyst is one of only a few active at 1 atm CO2, with turn-over-numbers up to 700 and turn-over-frequencies of 30 h-1. The catalyst has the advantage of being air stable, robust and able to polymerize unpurified (i.e. wet) cyclohexene oxide with no loss of activity. It is also moderately active under higher pressures (10 atm), with TONs up to 4000.
