Fig. 6. Systematic types of emerging reactivity patterns of actinide-nitrides suggested by this work and ref. 6b, 10i and 11b. (a) C–H activation of a R–H bond by a metal(vi)-nitride produces a metal(iv)-alkyl-amide by 1,1-insertion. (b) C–H activation of a R–H bond by a terminal or bridging metal(iv)-nitride produces a bridging or terminal metal(iv)-imido-alkyl by 1,2-addition; the R group can be coordinated to the metal(iv) ion or be eliminated with a group 1 metal.
