Zusammenfassung:
We present the synthesis and structural characterization of novel
ruthenium complexes containing C boolean AND C* cyclometalated
N-heterocyclic carbene ligands, eta(6)-arene (p-cymene) ligands and one
bridging chlorine ion. Complexes of the general formula [Ru(p-cymene)(C
boolean AND C*)Cl] were prepared via a one-pot synthesis using in situ
transmetalation from the correspondent silver NHC complexes. These
complexes react with sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]
borate (NaBAr4F) to form dinuclear complexes of the general structure
[Ru(p-cymene)(C boolean AND C*)-mu-Cl-(p-cymene)-(C boolean AND C*)
Ru](+)[BAr4F](-). Solid-state structures confirm that the
pseudo-tetrahedral coordination around the metal center with the
eta(6)-ligand aligned perpendicularly to the C boolean AND C* ligand and
the i-Pr group "atop" is retained in the bimetallic complexes.
