<p>In the ruthenium complexes of the general formula A or B, X<superscript>1 >and X<superscript>2>, independently of one another, are monodentate or polydentate anionic ligands, R, R' and R'', independently of one another, are hydrogen or substituted or unsubstituted C<subscript>1-20</highlight>-alkyl, C<subscript>6-20</highlight>-aryl or C<subscript>7-20</highlight>-alkylaryl radicals, and L<superscript>1 >and L<superscript>2>, 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 <bold>0 </highlight>to <bold>20 </highlight>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.</p> |
