Ruthenium complexes containing carboids

Abstract

In the ruthenium complexes of the general formula A or B, 1 X1 and X2, independently of one another, are monodentate or polydentate anionic ligands, R, R′ and R″, independently of one another, are hydrogen or substituted or unsubstituted C1-20-alkyl, C6-20-aryl or C7-20-alkylaryl radicals, and L1 and L2, independently of one another, are neutral electron donor ligands which are coordinated as carbenoids to the metal center and may be linked via a bridge W having 0 to 20 carbon atoms, which may be part of a cyclic or aromatic group and may be interrupted by heteroatoms, with the exception of C,N-heterocyclic five-membered ring systems.

Dependencies are inferred from the claim text.
