The synthesis of the cationic Pd complex [Pd(dmba)(PCH2-oxazoline)]Cl [PCH2-oxazoline = 2-oxazoline-2-ylmethyl)diphenylphosphine] (2) has allowed for the first time the observation of hemilabile behaviour for a phosphinooxazoline ligand. This molecular dynamics is stopped upon removal of the chloride anion, by reaction with either NH4PF6, which retains the cationic nature of the complex, or ButOK. The latter reaction leads to the formation of the first example of a Pd complex bearing an anionic phosphinooxazoline ligand, [Pd(dmba){Ph2PCH – -…C( – -…N)CH2CH2O}], abreviated [Pd(dmba)(PCH-oxazoline)] (7), the anionic charge resulting from the monodeprotonation of the PCH2 group. Following this methodology, the Ru complex [RuCl(p-cymene){Ph2PCH – -…C( – -…N)CH2CH2O}], abreviated [RuCl(eta6-p-cymene)(PCH-oxazoline)] (8) and containing this four-electron chelating anionic ligand, was prepared and shown to be more reactive for the catalytic transfer hydrogenation of acetophenone in propan-2-ol than the analogous complex bearing the neutral phosphinooxazoline ligand PCH2-oxazoline. The crystal structure of cis-[Pd{Ph2PCH – -…C( – -…N)CH2CH2O}2], abbreviated cis-[Pd(PCH-oxazoline)2] (6), was determined by X-ray diffraction.

Cerium-based materials such as ceria are increasingly used in catalytic reactions. We report here the synthesis of the first Ce-based metal-organic layer (MOL), Ce6-BTB, comprising Ce6 secondary building units (SBUs) and 1,3,5-benzenetribenzoate (BTB) linkers, and its functionalization for photocatalytic hydrogen evolution reaction (HER). Ce6-BTB was postsynthetically modified with photosensitizing [(MBA)Ir(ppy)2]Cl or [(MBA)Ru(bpy)2]Cl2 (MBA = 2-(5?-methyl-[2,2?-bipyridin]-5-yl)acetate, ppy = 2-phenylpyridine, bpy = 2,2?-bipyridine) to afford Ce6-BTB-Ir or Ce6-BTB-Ru MOLs, respectively. The proximity of photosensitizing ligands and Ce6 SBUs in the MOLs facilitates electron transfer to drive photocatalytic HER under visible light with turnover numbers of 1357 and 484 for Ce6-BTB-Ir and Ce6-BTB-Ru, respectively. Photophysical and electrochemical studies revealed a novel dual photoexcitation pathway whereby the excited photosensitizers in the MOL are reductively quenched and then transfer electrons to Ce6 SBUs to generate CeIII centers, which are further photoexcited to CeIII? species for HER.

A pyridyl triazole (pyta) modified sucrose ligand was prepared in a seven step synthesis using D-glucose as the protection group for D-fructose and starting from commercially available sucrose. After complexation with Ru(bpy)2Cl2 precursor, the sucrose-conjugated Ru complex of the general formula [Ru(bpy)2(L)]Cl2 was formed. Acidic cleavage of the D-glucose unit led to the first D-fructose conjugated metal complex via D-fructose C6 in literature. Additionally, pyta-modified D-fructose via C1 and the corresponding Ru complex were synthesized. All compounds were analyzed by Rf values, specific rotation, NMR, IR, UV/Vis and fluorescence spectroscopy, mass spectrometry and elemental analysis.

Condensation of (R)-2-aminobutanol with salicylaldehyde and 2-pyrrolecarbaldehyde gave the chiral chelate ligands HLL1* and HLL2*, respectively. The diastereomeric complexes (RRu,RC)- and (SRu,RC)-[(eta6-arene)Ru(LL 1*)Cl], eta6-arene = p-cymene (1a/1b), eta6-arene = benzene (2a/2b)1 and (RRu,RC)- and (SRu,RC)[(eta6-arene)Ru(LL 2*)Cl], eta6-arena = p-cymene (3a/3b), eta6-arene = benzene (4a/4b), which only differ in the ruthenium configuration, were prepared by the reaction of [(eta6-arene)RuCl2]2 with the anion of the corresponding ligand HLL*. X-ray analyses of 1a/1b and 3a/ 3b showed a structural peculiarity. The unit cell of these complexes contained diastereomers with the same configuration at the carbon atoms but opposite configuration at the metal centers in a 1:1 ratio. Weak intramolecular O-H…Cl hydrogen bridges were formed in all the complexes. 1H-NMR studies demonstrated the configurational lability at the Ru center. The iodo complexes (RRu,RC)- and (SRu,RC)-[(eta6-p-cymene)Ru(LL*)I], LL* = LL1* (5a/5b) and LL* = LL2* (6a/6b), were synthesized by halogen exchange.

Ru(bpy)32+ (bpy = 2,2′-bipyridyl) has been covalently attached to n-type SnO2 via condensation of surface hydroxyl groups with ruthenium (4-(trichlorosilylethyl)-4′-methyl-2,2′-bipyridine)bis(2,2′-bipyridine) bis(hexafluorophosphate)).A thick coating (ca. 1000 layers, based on the surface hydroxyl group concentration) was produced, presumably via oligomerization of hydrolyzed -SiCl3 groups.The coating, which was stable to organic solvents as well as to aqueous acids and bases, gave reversible cyclic voltammograms, with peak potentials shifted slightly from those of aqueous Ru(bpy)32+, but the number of electroactive molecules corresponding only to a few layers.The coated electrode gave a photocurrent about twice that observed for SnO2 in contact with aqueous 4mM Ru(bpy)32+, with a slightly red-shifted excitation spectrum.Only a small fraction of the electroactive molecules appeared to participate in excited-state electron transfer, although a steady-state current was supported, presumably by slow electron transfer from the outer layers.Prolonged illumination produces extensive hydrolysis of the outer layers of the coating, but a modest reduction of electroactivity, and only a slight decrease in photocurrent.The photocurrent increases with applied potential, then reaches a plateau, and falls off again near the reduction potential of Ru(bpy)32+*; the falloff is attributed to back-electron transfer via tunnelling through the thin space charge layer.

We developed a Ru/hemilabile-ligand-catalyzed nucleophilic aromatic substitution (SNAr) of aryl fluorides as the limiting reagents. Significant ligand enhancement was demonstrated by the engagement of both electron-rich and neutral arenes in the SNAr amination without using excess arenes. Preliminary mechanistic studies revealed that the nucleophilic substitution proceeds on a eta6-complex of the Ru catalyst and the substrate, and the hemilabile ligand facilitates dissociation of products from the metal center.

Three new [Ru(bpy)2X]+ complex ions, where bpy represents bipyridyl ligand and X denotes pyridyl diazolate or pyrazinyl diazolate coordination site, have been computationally designed and synthesized as pH-sensitive molecules. The choice of pyridyl and pyrazinyl moieties allows for the nitrogen content to vary, whereas the influence of the protonation site is quantified by using 1,2-diazolate and 1,3-diazolate derivatives. The absorption and emission properties of the deprotonated and protonated complex ions were characterized by UV-vis and photoluminescence spectroscopy as well as by time-dependent density functional theory. Protonation causes (1) a strong blue shift in the lowest energy 3MLCT ? S0 emission wavelengths, (2) a substantial increase in the emission intensity, and (3) a change in the character of the corresponding 3MLCT emitting states. The blue shift in the emission wavelength becomes less pronounced when the nitrogen content in the X-ligand increases and when going from 1,2- to 1,3-diazolate derivatives. The contrast in the emission intensity of the protonated/deprotonated forms is the highest for the complex ion, containing a 2-pyridyl derivative of the 1,2-diazolate. The complex ions are suggested as potential pH-responsive materials based on change in the color and intensity of the emitted radiation. The broad impact of the research demonstrates that the modification of the nitrogen content and position within the protonable ligands is an effective approach for modulation of the pH-optosensing properties of Ru-polypyridyl complexes.
