The reactivity of alkali metal capped Ce(iv) imido compounds [M(DME)2][Ce[double bond, length as m-dash]NArF(TriNOx)] (1-M with M = K, Rb, Cs and ArF = 3,5-bis(trifluoromethyl)phenyl) with CO2 and organic isocyanates has been evaluated. 1-Cs reacted with CO2 to yield an organocarbamate complex. Reaction of 1-K and 1-Rb with organic isocyanates yielded organoureate Ce(iv) complexes.
