Preparation, structure, and reactivity of a (pentamethylcyclopentadienyl)titanium dimer bridged by oxygen and tetramethylmethylenecyclopentadienyl

Preparation of the Metallocene Oxide Cluster Compound [(Cp2Zr)3(μ2-OH)3(μ3-O)+]BPh4- by Hydrolysis of Jordan's Cation [Cp2ZrCH3(THF)+]BPh4-

“…We have demonstrated this, for instance, by observing Fischer-Tropsch-type behavior of CH 2 groups edge-on-bonded to the framework of the (Cp 2 -ZrO) 3 pseudohexagonal framework. 1 In contrast to the related Cp 2 ZrdNR species, which are readily formed by -elimination pathways, 2 the group 4 metallocene oxides are often prepared by oxidative pathways, such as treatment of the respective Cp 2 M II substrates with a very mild oxidizing reagent, such as N 2 O 3 or even CO 2 .…”

Nitrogen Monoxide and Nitrous Oxide Binding and Reduction

“…Oxotransfer from N 2 O can lead to formation of metal-oxo complexes or oxidation of ligands contained in the metal complex. In pioneering research of N 2 O reactivity, Bottomley and coworkers [188][189][190][191][192] N 2 O insertion into a metal-ligand bond has been observed with Group IV metallocene complexes (Scheme 2.9) [194]. When reported, these transformations were unprecedented since reactions between N 2 O and metal complexes usually lead to extrusion of N 2 .…”

Synthesis, Characterisation, Crystal Structures, Reactivity, and Electrochemistry of Ruthenium-Nitrido, Ruthenium-Cobalt-Imido and Ruthenapyrrolidone Carbonyl Clusters Containing Alkyne Ligands

“…In contrast, the C(10), which belongs to the methylene group s-bonded to the Ru(2) atom, is displaced from the Cpring plane by 0.123 in the direction of the Ru(1) atom. [43] The Ru(1)ÀC(10) and Ru(1)ÀC (11) bond lengths of of 2.90 and 2.26(1) , respectively, indicate that there is no interaction between the methylene group and Ru (1). This C 5 plane is 1.878 from the Ru(1) atom.…”
