Transition Metal Carbide Complexes

Chemical Reviews, 2021
Carbide complexes remain a rare class of molecules. Their paucity does not reflect exceptional instability but is rather due to the generally narrow scope of synthetic procedures for constructing carbide complexes. The preparation of carbide complexes typically revolves around generating LnM-CEx fragments, followed by cleavage of the C-E bonds of the ...

Transition metal borylene complexes

Chemical Society Reviews, 2013
Borylene ligands (:BR) are isolobal to CO and other iconic organometallic ligands. As such, borylene ligands enjoy some parallels to these ligands, but in many ways, their chemistry is distinct. This tutorial review gives an introduction to the synthesis, properties and reactivity of the major classes of transition metal borylene complexes, including ...

Transition metal complexes

Journal of Organometallic Chemistry, 1993
The invention relates to transition metal complexes of general formulas (Ia) or (Ib) in which the substituents and indices have the following meanings: M represents titanium, zirconium, hafnium, vanadium, niobium or tantalum or an element of the third subgroup of the periodic table or of the lanthanides; X represents fluorine, chlorine, bromine, iodine,

Early Transition-Metal Perfluoroalkyl Complexes

Journal of the American Chemical Society, 2003
Elusive early transition-metal perfluoroalkyl complexes have been isolated and structurally characterized for the first time. Trifluoromethyltrimethylsilane, CF3SiMe3, serves as an excellent trifluoromethyl group-transfer reagent and reacts with the known Ti(IV) fluoride complex Cp2TiF2 to yield the novel Ti(IV) trifluoromethyl fluoride compound, Cp2Ti(

Bridging vinylalkylidene transition metal complexes

Coordination Chemistry Reviews, 2010
Abstract Vinylalkylidene transition metal complexes have been extensively used as ‘multitalent tools’ in organic synthesis, covering a broad field of applications. The vinylalkylidene ligands can be monodentate; alternatively they can adopt a bridging coordination mode in complexes with two adjacent metal atoms.

Transition metal O-sulphinate complexes

Inorganica Chimica Acta, 1968
Abstract This paper reports the preparation and characterisation of sulphinate complexes of palladium and platinum. The structure of the complexes has been investigated using both infrared spectroscopy and chemical reactivity. It is concluded that the sulphinate ligand in all these complexes behaves as a terminal, sulphur bonded ligand. The action of

Divalent transition metal complexes

Journal of Thermal Analysis and Calorimetry, 2005
4-(4-ethoxy-phenylhydrazono)-1-phenyl-3-methyl-1H-pyrazolin-5(4H)-one (5a) (H-EMPhP) as ligand and its Cu(II), Co(II) and Ni(II) complexes 4(a-c) were synthesized and characterized by their thermal and spectral properties. The azocoupling product (H-EMPhP), able of azo-hydrazone tautomerism 5(a-d), act as a bidentate ligand involving in coordination ...
