Abstract
The intramolecular metalation of a beta-silyl methyl group in [U{N(CH2CH2NS iMe2But)(3)}(CH2Ph)] occurs rapidly, despite the conformational demands of the triamidoamine ligand, to produce a highly strained metallacycle (U-C ca . 2.75 Angstrom); this complex reacts cleanly with a range of carbon and ot her acids to give, for example, an alkynyl with a bent (156 degrees) U-C=C unit.
