Supramolecular assemblies with symmetrical octahedral structures – Synthesis, characterization, and electrochemical properties

Functional nanosized cage complexes with an octahedral framework have been synthesized by the facile self-assembly reactions of six 90 Pd II-containing compounds {[Pd(dppf)(OTf)2] or [Pd(PPh 3)(OTf)2], dppf = 1,1?-bis(diphenylphosphanyl) ferrocene, OTf = trifluoromethylsulfonate} and four 120 functional tritopic ligands [2,4,6-tri(4-pyridyl)-1,3,5-triazine] in acetone. Diffusion-ordered NMR spectroscopy (DOSY) and AFM images clarify the formation of 3-4 nm nanoparticles. These highly symmetrical cage complexes are discrete, face-directed, functional nanoparticles with symmetrical octahedral structures. The self-assembled functional cage complexes exhibit interesting electrochemical activities, and thus will potentially be useful in the catalysis of redox reactions, the encapsulation of sizeable guest molecules and the control of organic synthetic reactions. The appropriate stoichiometric combination of 90 PdII-containing units with 120 tritopic units affords octahedral symmetrical nanocages through covalently linked functional groups, which exhibit interesting electrochemical activities.

Design, Synthesis, Structure-Activity Relationship Studies, and Three-Dimensional Quantitative Structure-Activity Relationship (3D-QSAR) Modeling of a Series of O-Biphenyl Carbamates as Dual Modulators of Dopamine D3 Receptor and Fatty Acid Amide Hydrolase

We recently reported molecules designed according to the multitarget-directed ligand paradigm to exert combined activity at human fatty acid amide hydrolase (FAAH) and dopamine receptor subtype D3 (D3R). Both targets are relevant for tackling several types of addiction (most notably nicotine addiction) and other compulsive behaviors. Here, we report an SAR exploration of a series of biphenyl-N-[4-[4-(2,3-substituted-phenyl)piperazine-1-yl]alkyl]carbamates, a novel class of molecules that had shown promising activities at the FAAH-D3R target combination in preliminary studies. We have rationalized the structural features conducive to activities at the main targets and investigated activities at two off-targets: dopamine receptor subtype D2 and endocannabinoid receptor CB1. To understand the unexpected affinity for the CB1 receptor, we devised a 3D-QSAR model, which we then prospectively validated. Compound 33 was selected for PK studies because it displayed balanced affinities for the main targets and clear selectivity over the two off-targets. 33 has good stability and oral bioavailability and can cross the blood-brain barrier.

Preparation of 2-arylated-1,4-phenylenediamines by palladium-catalyzed cross-coupling reactions

Protected 2-iodol-1,4-phenylenediamines were converted to the corresponding magnesium derivative by performing an iodine-magnesium exchange. After transmetalation with zinc bromide, a palladium(0)-catalyzed cross-coupling with various aryl iodides and 5-bromo-2-carbethoxyfuran furnished the expected cross-coupling products in 52-79% yield.

New building blocks for the noncovalent assembly of homo- and hetero-multinuclear metallodendrimers

Ligands 5 and 8, derived from the coupling of [3,5-bis[(diphenylphosphinyl)methyl]phenyl]-oxy groups to bi- and trifunctional spacers, respectively, were cyclometalated with Pd[CH3-CN]4(BF4)2, cis-[PtCl2(PPh3)2], or NiCl2·-6H2O. The cationic Pd and Pt complexes were converted into overall neutral Pd-Cl and Pt-Cl complexes. The resulting pincer complexes can be used as building blocks for the controlled assembly of both homo- and hetero-multinuclear metallodendrimers. The 31P NMR spectra of the pincer complexes exhibit different shifts for chloride, H2O, or nitrile occupying the fourth coordination site, making the 31P chemical shift an excellent diagnostic tool for the assembly process.

Redox-coupled complexation of 23-phospha-21-thiaporphyrin with group 10 metals: A convenient access to stable core-modified isophlorin-metal complexes

Core-modified isophlorin-metal complexes were successfully prepared by redox-coupled complexation of P,S,N2-hybrid porphyrin with zerovalent palladium, nickel, and platinum. In this transformation, the core-phosphorus atom plays crucial roles in enhancing the electron-accepting ability of the 18pi porphyrin ring and stabilizing the 20pi isophlorin ring owing to high P-M affinity. The isolated Pd and Pt complexes are chemically stable under ambient conditions. The Pd-P,S,N2 isophlorin complex was structurally characterized by X-ray crystallography, which revealed a distorted 20pi plane with a square planar palladium(II) center. Experimental (1H, UV-vis, and X-ray) and theoretical (density functional theory calculations) results suggest that the P,S,N2-isophlorin-metal complexes possess nonaromaticity in terms of both magnetic and geometrical criteria.

Selective oxidative carbonylation of amines to oxamides and ureas catalyzed by palladium complexes

A new process for converting secondary amines into N,N,N?,N?- tetraalkyloxamides under CO pressure, catalyzed by homogeneous palladium complexes in the presence of 1,4-dichloro-2-butene (DCB) as an oxidant, has been developed. The mechanism of the oxidative double-carbonylation process, consisting of the oxidation of Pd(0) to Pd(11) with DCB through a beta-chloride elimination of the eta3-(chloromethyl) allylpalladiuni(11) intermediate, the formation of mono- and bis(carbamoyl)palladium species, and a reductive elimination of the two carbamoyl ligands, is proposed based on studies of the behavior of carbamoylpalladium complexes. When primary amines are employed with DCB as the oxidant, N,N?-dialkyloxamide is catalytically produced, whereas urea is exclusively produced when iodine is used as the oxidant. The reaction of an N-monopropylcarbamoylpalladium complex with propylamine under CO gave N,N?-dipropylurea, whereas a treatment with diethylamine yielded unsymmetrical N,N-diethyl-N?-propylurea, implying the intermediate formation of propyl isocyanate that is converted into the urea upon a reaction with the added amine. A kinetic study on the reaction of chloro-N- propylcarbamoylpalladium with triethylamine suggested a process proceeding through a base-promoted dcprolonalion of the N-monoalkylcarbamoyl ligand to form propyl isocyanate.

Effect of Perylene Photosensitizer Attachment to [Pd(triphosphine)L]2+ on CO2 Electrocatalysis

Two new covalently linked chromophore-CO2 reduction catalyst systems were prepared using a perylene chromophore and a bis[(dicyclohexylphosphino)ethyl]phenylphosphinopalladium(II) catalyst. The primary goal of this study is to probe the influence of photosensitizer attachment on the electrocatalytic performance. The position either para or meta to the phosphorus on the phenyl group of the palladium complex was linked via a 2,5-xylyl group to the 3 position of perylene. The electrocatalytic CO2 reduction activity of the palladium complex is maintained in the meta-linked system, but is lost in the para-linked system, possibly because of unfavorable interactions of the perylene chromophore with the glassy carbon electrode used. Following selective photoexcitation of the perylene, an enhanced perylene excited-state decay rate was observed in the palladium complexes compared to perylene attached to the free ligands. This decrease is accompanied by formation of the perylene cation radical, showing that electron transfer from perylene to the palladium catalyst occurs. Electron transfer and charge recombination were both found to be faster in the para-linked system than in the meta-linked one, which is attributed to stronger electronic coupling in the former. These results illustrate the need to carefully tune the electronic coupling between a photosensitizer chromophore and the catalyst to promote photodriven electron transfer yet inhibit adverse electronic effects of the chromophore on electrocatalysis.
