Stille-type cross-coupling procedures are utilized in order to prepare a variety of functionalized 2,2?-bipyridines and 2,2?:6?,2?-terpyridines. Such N-heterocyclic compounds are of great interest as chelating ligands for transitionmetal ions in the field of supramolecular chemistry. Various mono- and disubstitued 2,2?-bipyridines were synthesized in high yields and multigram scales using a modular design principle. The terpyridines may be functionalized in one step with different substituents at the outer pyridine rings and at the 4?-position of the centered ring, leading to multifunctionalized compounds. The initially obtained methyl ester and ethyl ester groups can be simply converted into bromomethyl and hydroxymethyl groups which allow further functionalization reactions.

We have investigated light-triggered or catalytically activated precipitation agents and have proposed the name “precipiton” for such molecules or molecular fragments. A phase separation Is induced when the precipiton isomerizes to a low-solubility form. In this paper we describe the first intramolecularly activated precipitons. The isomerization process is induced by intramolecular triplet energy transfer from a covalently attached metal complex. As expected, intramolecular sensitization leads to a more rapid isomerization than can be achieved by intermolecular sensitization at accessible concentrations. Two isomeric bichromophoric precipiton species, each containing [Ru(bpy)3]2+ and 1,2-bis(biphenyl)ethene units covalently linked together by an ether tether, have been synthesized and characterized, and their photochemical properties have been investigated. The rates of photoisomerization of these complexes, [((Z)-1,2-bis(biphenyl)ethene-bpy)Ru(bpy) 2](PF6)2 (2Z) and [((E)-1,2-bis(biphenyl) ethene-bpy)Ru(bpy)2](PF6)2 (2E), were compared to those of their untethered analogues, (Z)-1,2-bis(biphenyl)ethene-OTBS (1Z) and (E)-1,2-bis(biphenyl)ethene-OTBS (1E), where ruthenium sensitization occurred through an intermolecular pathway. Upon irradiation with visible light (lambda ? 400 nm) in degassed solution, 2Z/E and 1Z/E obeyed reversible first-order rate kinetics. The intramolecularly sensitized precipiton 2Z isomerized 250 times faster (k2Z-2E = 1.0 × 10-3 s-1 with a 51% neutral density filter) than the intermolecular case 1Z (k1Z-1E = 0.80 × 10-5 s-1). For 1E and 2E, the isomerization rates were k1E-1Z = 11.0 × 10 -5 s-1 and k2E-2Z = 1.6 × 10-3 s-1, respectively. The average Z/E mole ratio at the photostationary state was 62/38 for 2Z/E and 93/7 for 1Z/E. The impetus for this study was our desire to evaluate the possibility of using metal-binding precipitons that would precipitate only upon metal-to-precipiton binding and would be inert to visible light in the absence of metals.

A novel ruthenium(II) polypyridyl complex connected covalently to a bolaamphiphile, containing amide linkages to provide rigidity via hydrogen bonding in the monolayer, has been prepared. The ruthenium(II) complexes of this ligand and of the intermediates in the synthesis were prepared by modification of the coordinated ligands, demonstrating the synthetic versatility and robustness of this family of complexes. All ruthenium complexes were characterised by electrochemical and spectroscopic techniques and were found to have similar properties to the parent complex [Ru(bipy)3]2+, and remain versatile photosensitisers, with well-defined properties, despite extensive substitution of the bipy ligand.

Metal-directed assembly of combinatorial libraries – Principles and establishment of equilibrated libraries with oligopyridine ligands

The cobalt(ii) complexes [Co(bpy)3][PF6]2, [Co(Me2bpy)3][PF6]2 (Me 2bpy = 4,4?-dimethyl-2,2?-bipyridine) and [Co(phen) 3][PF6]2 give paramagnetically shifted 1H NMR spectra which may be fully assigned; the complexes are labile and ligand exchange is complete within mixing time in CD3CN solutions to give libraries of heteroleptic complexes which have been fully characterised by one- and two-dimensional 1H NMR spectroscopy. A library comprising mer and fac isomers of [CoL3]2+ (L = 2,2?-bipyridine-5-carbaldehyde) can be amplified by specific reaction of the fac stereoisomer with a triamine to give a new hexadentate ligand, although other ligand exchange processes compete.

Effect of 5-Me substituent(s) on the catalytic activity of palladium(II) 2,2?-bipyridine complexes in CO/4-tert-butylstyrene copolymerization

The coordination of two 5-substituted-2,2?-bipyridines L (L1=5-methyl-2,2?-bipyridine, L2=5,5?-dimethyl-2,2? -bipyridine) to palladium was studied. The neutral complexes [Pd(L)Cl2] and [Pd(L)(Me)Cl], and the cationic complexes obtained after chlorine abstraction [Pd(L)2] [BAr?4]2 and [Pd(L)(Me)(NCMe)] [BAr?4] (Ar?=3,5- (CF3)2-C6H3), respectively, were isolated and characterized by NMR and FAB mass spectroscopy. The complex [Pd(L2)(L3)][BAr? 4]2 (L3=2,2? -bipyridine) bearing different ligands, was prepared for comparison purposes. The activity of the monocationic and dicationic complexes as catalytic precursors in the CO/4- tert -butylstyrene copolymerization was compared with that of related well-known catalysts containing the unsubstituted 2,2?-bipyridine as nitrogen ligand, to evaluate the influence of the substituents in 5- and 5,5?-position. The presence of one or two substituents on the nitrogen ligand has a positive effect on productivity using both types of precursors. No influence was observed on the polymer properties in terms of molecular weight and tacticity. Analysis of the reactivity of the methyl-palladium complexes towards carbon monoxide shows further differences depending on the nitrogen ligand.

RuII Photosensitizer-Functionalized Two-Dimensional MoS2 for Light-Driven Hydrogen Evolution

Metallic-phase molybdenum disulfide (1T-MoS2) nanosheets have proven to be highly active in the hydrogen evolution reaction (HER). We describe construction of photosensitizer functionalized 1T-MoS2 by covalently tethering the molecular photosensitizer [RuII(bpy)3]2+ (bpy=2,2?-bipyridine) on 1T-MoS2 nanosheets. This was achieved by covalently tethering the bpy ligand to 1T-MoS2 nanosheets, and subsequent complexation with [RuII(bpy)2Cl2] to yield [RuII(bpy)3]?MoS2. The obtained [RuII(bpy)3]?MoS2 nanosheets were characterized using infra-red, electronic absorption, X-ray photoelectron, and Raman spectroscopies, X-ray powder diffraction and electron microscopy. The fabricated material exhibited a significant improvement of photocurrent and HER performance, demonstrating the potential of such two-dimensional [RuII(bpy)3]?MoS2 constructs in photosensitized HER.
