Reactivity of the actinoid–carbon σ bond: reaction of [(Me3Si)2N]2MCH2Si(Me)2NSiMe3 with acidic hydrogen, ready C–H activation
Abstract
The metal-carbon bond of the four-membered metallacycles [(Me3Si)2N]2[graphic ommitted]SiMe3(M = U,Th) reacts under mild conditions with acidic hydrogen of alcohols, phenols, and alkynes, with pyridine to give the orthometallated products from sp2C–H activation, and with metal hydrides to five stable binuclear compounds with an isocarbonyl linkage, whereas cyclopentadienes cleave the metal–nitrogen bond providing biscyclopentadienyl four-membered metallacycles.
