A trimetallic mixed Ru(II)/Fe(II) terpyridyl complex with a long-lived excited state in solution at room temperature

The photophysical behavior of a series of mono- and trimetallic Ru(II) and mixed Ru(II)/Fe(II) bis-terpyridyl complexes was examined. The complexes have bridging terpyridyl ligands linked by phenylene-vinylene substituents on the terpyridyl. For the complexes bridged by a single phenylene-vinylene, the lowest-energy excited state is metal-to-ligand charge transfer (MLCT), and excited-state decay is on the 1-10 ns time scale. The complexes with two phenylene-vinylene groups have thermally equilibrated excited states that are localized on the phenylene-vinylene bridge and have much longer lifetimes (>200 ns). Remarkably, the trimetallic complex having an Fe(II) terpyridyl center also has a long-lived excited state, despite the fact that low-energy iron-localized excited states exist on the complex.

Synthetic routes to a coordinatively unsaturated ruthenium complex supported by a tripodal, protic bis(N-heterocyclic carbene) phosphine ligand

A facile, one pot synthesis of a coordinatively unsaturated ruthenium complex supported by a tripodal, protic bis(N-heterocyclic carbene) phosphine ligand is presented. A number of coordination complexes were discovered en route during this synthesis, revealing some of the unique aspects of complexes ligated by this type of tridentate, protic bis(NHC) ligand. Through a combination of 1D and 2D NMR spectroscopic analysis and single crystal X-ray diffraction, we reveal the intermediacy of phosphine-ligated bisimidazole complexes and show that abstraction of inner-sphere halide ions facilitates conversion to the desired tridentate bis(NHC) coordination mode. Ultimately the use of N-methyl-2-pyrrolidone is shown to enable the use of the extreme temperatures needed to facilitate the direct, thermally activated tautomerization reaction that gives rise to the bis(NHC) motif.

Controlled formation of mixed-metal macrocycles using dynamic exchange processes and steric constraints

The exchange reaction of the trinuclear macrocycles [(C6H 3iPr3)Ru(C5H3NO2)] 3 (AAA) and [(cymene)Ru(C5H3NO 2)]3 (BBB) has been studied. It was found that the equilibration proceeds in two steps and that the final mixture is completely dominated by the mixed-metal macrocycles [{(C6H3iPr 3)Ru}2{(cymene)Ru}(C5H3NO 2)3] (AAB) and [{(C6H3iPr 3)Ru}{(cymene)Ru}2(C5H3NO 2)3] (ABB). The results are rationalized by assuming unfavorable steric interactions between adjacent (C6H 3iPr3)Ru fragments. It is shown that interactions of this kind can be used to bias scrambling processes in such a way that mixed-metal macrocycles are obtained in over 80 % yield. The structures of [{(C 6Me6)Ru){(C6H6)Ru} 2(C5H3NO2)3] and [(Cp*Rh){(C6H6)Ru}2(C5H 3NO2)3] have been determined by single-crystal X-ray analysis. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Highly selective metathesis of 1-octene in ionic liquids

The self-metathesis of 1-octene to form 7-tetradecene catalyzed by ruthenium carbene complexes at low concentrations (0.02 mol %) was investigated in ionic liquids as reaction media and as additives. The study showed that the ionic liquid has a significant effect on the selectivity of the metathesis of 1-octene, with conversion to product of greater than 95% being obtained and selectivities of over 98% being realized. The outcomes of the reactions compared well with those performed under solventless conditions, showing improved conversions and selectivittes.

Substituted pyridazines as ligands in homoleptic (fac and mer) and heteroleptic Ru(ii) complexes

This article reports the preparation of a range of phenyl, pyridyl and pyrazinyl substituted pyridazines via the inverse electron demand [2 + 4] Diels-Alder reaction between 3,6-di(2-pyridyl)-1,2,4,5-tetrazines (bptz) and 3,6-di(2-pyrazinyl)-1,2,4,5-tetrazines (bpztz) and suitable dienophiles including acenaphthalene. The resulting polyaromatic compounds vary systematically in the number of aromatic substituents and the number and position of N-heteroatoms. For four of these compounds, the effect of the molecular changes on the solid-state structures were investigated using single crystal X-ray crystallography. The pyridazines were used as bidentate ligands in {M(ii)(bipy)2} and tris(homoleptic) complexes (M = Fe, Ru). The optical and electrochemical properties of these complexes reflect the electron accepting character of the new ligands. The facial and meridional isomers of the tris complexes could be separated by column chromatography (on silica), thus allowing a spectral comparison of their absorption and emission properties. The solid-state structures of several of the metal complexes are discussed, including that of the facial isomer of the tris Ru(ii) complex of 3,6-bis(2-pyridyl)-4,5-bis(4-pyridyl)pyridazine – a potential preformed geometric motif for the predirected construction of supramolecular assemblies.
