title: Zirconium and titanium amido complexes with 3,3-dimethyl-1,5-diaza-8-oxacyclodecane; facile C-H activation of the macrocyclic rim.
abstract: Reaction of the dilithium salt of 3,3-dimethyl-1,5-diaza-8-oxacyclodecane, [(NLi)2O], with Zr(NEt2)2Cl2(thf)2 gave the formally 20e- complex [Zr(N2O)2]; metallation of the macrocycle [(NH)2O], with Ti(benzyl)4 gave rise to [(N2O)*Ti(benzyl)]2 in which the trianionic diamido (N2O)* was formed by an unprecedented C-H activation of the carbon [small alpha] to the amido nitrogen.
