摘要：
(Chemical Equation Presented) Cubic cages: The alkynylimido clusters 2 ([Ti]=Ti(η5-C5Me5); R = SiMe3, Ph) are formed upon reaction of 1 with terminal alkynes. Density functional calculations show that the process involves a two-electron reduction of the Ti3 fragment. A concerted C-H activation, which leads to an alkynyl titanium complex, is followed by alkynyl migration to the apical nitrido ligand (see picture). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
