The reaction of equimolar amounts of AgI and the ligand bis(2-(diphenylphosphino)phenyl)ether (DPEphos) in the ionic liquid [NMe(n-Bu)3]2[N(Tf)2] yields the dinuclear complex Ag2I2(DPEphos)2. Herein, each silver atom is coordinated by two iodide anions and two DPEphos ligands, resulting in a distorted tetrahedral coordination. Moreover, Ag-Ag interaction (293.7 pm) is observed and represents the shortest bonding observed for dinuclear silver phosphine complexes.

We report the synthesis and characterisation of new examples of meso-hydroxynickel(II) porphyrins with 5,15-diphenyl and 10-phenyl-5,15-diphenyl/diaryl substitution. The OH group was introduced by using carbonate or hydroxide as nucleophile by using palladium/phosphine catalysis. The NiPor-OHs exist in solution in equilibrium with the corresponding oxy radicals NiPor-O.. The 15-phenyl group stabilises the radicals, so that the 1H NMR spectra of {NiPor-OH} are extremely broad due to chemical exchange with the paramagnetic species. The radical concentration for the diphenylporphyrin analogue is only 1 %, and its NMR line-broadening was able to be studied by variable-temperature NMR spectroscopy. The EPR signals of NiPor-O. are consistent with somewhat delocalised porphyrinyloxy radicals, and the spin distributions calculated by using density functional theory match the EPR and NMR spectroscopic observations. Nickel(II) meso-hydroxy-10,20-diphenylporphyrin was oxidatively coupled to a dioxo-terminated porphodimethene dyad, the strongly red-shifted electronic spectrum of which was successfully modelled by using time-dependent DFT calculations.

There is a need for high-quality screening collections that maximise hit rate and minimise the time taken in lead optimisation to derive a candidate drug. Identifying and accessing molecules that meet these criteria is a challenge. Within central nervous system (CNS)-focused drug discovery, this challenge is heightened by the requirement for lead compounds to cross the blood?brain barrier. Herein, we demonstrate use of a multiparameter optimisation tool to prioritise the synthesis of molecular scaffolds that, when subsequently decorated, yield screening compounds with experimentally determined properties that align with CNS lead generation needs. Prospective use of this CNS Lead Multiparameter Optimisation (MPO) scoring protocol can guide the further development of novel synthetic methodologies to access CNS-relevant and lead-like chemical space.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.166330-10-5, Name is (Oxybis(2,1-phenylene))bis(diphenylphosphine), molecular formula is C36H28OP2. In a Article，once mentioned of 166330-10-5, Formula: C36H28OP2

A new series of mononuclear copper(I) complexes (1-9) with functionalized 3-(2′-pyridyl)-1,2,4-triazole chelating ligands, as well as the halide and/or phosphine ancillary ligands, have been synthesized. Complexes 1-9 were fully characterized by elemental analysis, NMR spectroscopy, mass spectroscopy, electronic absorption spectroscopy, fluorescence spectroscopy, cyclic voltammetry, and X-ray crystallography (1-8). They adopt a distorted tetrahedral configuration, and are considerably air-stable in solid state and in solution. All these Cu(I) complexes display a comparatively weak low-energy absorption in CH2Cl2 solution, assigned to charge-transfer transitions with appreciable MLCT character, as supported by TD-DFT studies. Cu(I) halide complexes 1-4 each shows bright solid-state emission at room temperature, although they are nonemissive in fluid solutions, in which the emission markedly depends on the halide and the substituent on the 2-pyridyl ring. Complexes 5-9 bearing 2-pyridyl functionalized 1,2,4-triazole and phosphine exhibit good photoluminescence properties in solution and solid states at ambient temperature, which are well-modulated via the alteration of the auxiliary phosphine ligand and the structural modification of 3-(2′-pyridyl)-1,2,4- triazole. Interestingly, cationic complex 6 and neutral derivative 7 can readily be interconverted through the ring inversion of the 1,2,4-triazolyl regulated by the NH a?” N- transformation.

A great deal of research effort has been put in green energy applications in the past few decades based on organic optoelectronics. Compared with conventional inorganic semiconductors, organic counterparts offer a much simpler strategy for low-cost mass production and structural modification. Hence, continuous and intensive academic and industrial research works have been done in these areas. In terms of the materials used, transition-metal complexes with the unique features of the transition metal centers represent a large group of candidates, showing high performance in energy conversion technologies. However, the commonly used transition metals, like Pt(II), Ir(III) and Ru(II), are expensive and of relatively low abundance. Concerning elemental sustainability and marketability, some abundant and cheaper metals should be investigated and further developed to replace these precious metals. Cu(I) complexes have shown their potentiality in solar energy harvesting and light emitting applications, due to their well-studied photophysics and structural diversity. In addition, copper is one of the earth-abundant metals with less toxicity, which makes it competitive to precious transition metals. As a result, a series of rational molecular engineering has been developed to boost the device performance of copper complexes. In this review, the recent progress of copper complexes in the fields of organic light emitting devices (OLEDs), photovoltaic cells (dye-sensitized solar cells (DSSCs) and bulk heterojunction solar cells (BHJSCs)) in the past two decades will be presented. Representative examples are chosen for discussion.

Palladium(II) dialkyl complexes have previously been studied for their formation of alkanes through reductive elimination. More recently, these complexes, especially L2Pd(CH2TMS)2 derived from Pd(COD)(CH2TMS)2, have found general use as palladium(0) precursors for stoichiometric formation of oxidative addition complexes through a two-electron reductive elimination/oxidative addition sequence. Herein, we report evidence for an alternative pathway, proceeding through single-electron elementary steps, when DPEPhosPd(CH2TMS)2 is treated with an alpha-bromo-alpha,alpha-difluoroacetamide. This new pathway does not take place through a palladium(0) intermediate, neither does it afford the expected oxidative addition complexes. Instead, stoichiometric amounts of carbon-centered alkyl radicals are formed, which can be trapped in high yields either by TEMPO or by an arene, leading to alpha-aryl-alpha,alpha-difluoroacetamides. The same overall transformation takes place under both thermal conditions (70 C) and irradiation with a household light bulb (at 30 C). It is also demonstrated that DPEPhosPdMe2, made in situ from Pd(TMEDA)Me2, displays a similar initial reactivity. Finally, electronically and structurally different alkyl bromides were evaluated as reaction partners.

A series of [ReBr2(MeCN)(NO)(P?P)] complexes (P?P = 1,10-bis(diphenylphosphino)ferrocene (dppfc) (1a), 1,10- bis(diisopropylphosphino)ferrocene (diprpfc) (1b), 2,20-bis(diphenylphosphino) diphenyl ether (dpephos) (1c), 10,11-dihydro-4,5-bis(diphenylphosphino) dibenzo[b,f]oxepine (homoxantphos) (1d), 4,6-bis(diphenylphosphino)-10,10- dimethylphenoxasilin (Sixantphos) (1e)) were prepared with diphosphines varying in the P-Re-P bite angles. 1a,c-e were obtained from the reaction of [ReBr 5(NO)][NEt4]2 with an excess of the respective diphosphine in MeCN or MeCN/THF mixtures at elevated temperatures. Compound 1b was obtained by an alternative route, cleaving the dinuclear [{ReBr(mu2- Br)(NO)(diprpfc)}2] unit (2b) with MeCN. 2b was prepared from the reaction of [ReBr5(NO)][NEt4]2 with diprpfc in EtOH. The reaction of 1a-d with HSiEt2 gave the seven-coordinate [ReBr(H)2(SiEt3)(NO)(PnP)] compounds 4a-d, of which 4a,c,d are only stable in solution in the presence of HSiEt3. The SiMe3 (4f) and SiCl3 (4g) derivatives of 4b were also prepared by applying the reaction of 1b with HSiMe3 and HSiCl3. 1a,c,e, 2b, and 4f,g were structurally characterized. For 1c,e, 2b, and 4f,g NO/Br disorder was observed, which originates from the presence of two isomeric forms in the crystals of the respective compounds. For 1c,d fast interconversion of these isomers could be observed in their 31P{1H} NMR spectra at room temperature.
