Abstract

The reaction of [RuCl3(AsPh3)(2)(MeOH)] with the dimeric complexes (cod)RhCl, (ppy)RhCl (ppy = cyclometalated 2-phenylpyridine), (cymene)RuCl2 and CP*MCl2 (M = Rh, Ir) has been investigated. The structure of the resulting products was shown to depend on the reaction partner. Whereas for the rhodium complexes (cod)RhCl and (ppy)RhCl, heterobimetallic compounds with two halogeno-bridges were found, the reactions with the halfsandwich complexes (cymene)RuCl2 and CP*MCl2 gave triply bridged products with concomitant formation of mononuclear [(pi-ligand)MCl2(AsPh3)] side products. The new complexes were all characterized by single crystal X-ray analysis. (C) 2004 Elsevier B.V. All rights reserved.

Ligand

In coordination chemistry, a ligand is an ion or molecule with a functional group that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electron pairs, often through Lewis bases. The nature of metal–ligand bonding can range from covalent to ionic. Furthermore, the metal–ligand bond order can range from one to three. Ligands are viewed as Lewis bases, although rare cases are known to involve Lewis acidic "ligands".

Metallocene

A metallocene is a compound typically consisting of two cyclopentadienyl anions (C5H5−, abbreviated Cp) bound to a metal center (M) in the oxidation state II, with the resulting general formula (C5H5)2M. Closely related to the metallocenes are the metallocene derivatives, e.g. titanocene dichloride or vanadocene dichloride. Certain metallocenes and their derivatives exhibit catalytic properties, although metallocenes are rarely used industrially. Cationic group 4 metallocene derivatives related to [Cp2ZrCH3]+ catalyze olefin polymerization.

Cross-coupling reaction

In organic chemistry, a cross-coupling reaction is a reaction where two different fragments are joined. Cross-couplings are a subset of the more general coupling reactions. Often cross-coupling reactions require metal catalysts. One important reaction type is this: (R, R' = organic fragments, usually aryle; M = main group center such as Li or MgX; X = halide) These reactions are used to form carbon–carbon bonds but also carbon-heteroatom bonds. Cross-coupling reaction are a subset of coupling reactions.
