Abstract

The reactivity of alkali metal capped Ce(iv) imido compounds [M(DME)₂][Ce[double bond, length as m-dash]NAr^F(TriNOx)] (1-M with M = K, Rb, Cs and Ar^F = 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.
