In the presence of phosphine chalcogenoniobates such as Li3[NbS4] · 4 CH3CN (I), (NEt4)4[Nb6S17] · 3 CH3CN (II) and (NEt4)2[NbE?3(EBu)] (IIIa: E? = E = S; IIIb: E = Se, E? = S; III c: E = E? = Se) respectively react with copper and gold salts to give a number of new heterobimetallic niobium copper(gold) chalcogenide clusters. These clusters show metal chalcogenide units already known from the complex chemistry of the tetrachalcogenometalates [ME4]n- (M = V, n = 3, E = S; M = Mo, W, n = 2, E = S, Se). The compounds 1-8 owe a central tetrahedral [NbE4] structural unit, which coordinates eta2 from two to five coinage metal atoms, employing the chalcogenide atoms of the [NbE4] edges. The compounds 9-11 have a [M?2Nb2E4] (M? = Cu, Au) heterocubane unit in common, involving a metal metal bond between the niobium atoms, while the compounds 12 and 13 show a complete and 14 an incomplete [M?3NbE3X] heterocubane structure (X = Cl, Br). 15 consists of a Cu6Nb2 cube with the six planes capped by mu4 bridging selenide ligands forming an octahedra. The compounds 1-15 are listed below: (NEt4)?1[Cu2NbSe 2S2(dppe)2] · 2 DMF (1), [Cu3NbS4(PPh3)4] (2), [Au3NbSe4(PPh3)4] · Et2O (3), [Cu4NbS4Cl(PCy3)4] (4), [Cu4NbS4Cl(PBu3)4] · 0,5 DMF (5), [Cu4NbSe4(NCS)(PBu3)4] · DMF (6), [Cu4NbS4(NCS)(dppm)4] · Et2O (7), [Cu5NbSe4Cl2(dppm)4] · 3 DMF (8), [Cu2Nb2S4Cl2(PMe3) 6] · DMF (9), [Au2Nb2Se4Cl2(PMe3) 6] · DMF (10), (NEt4)2[Cu3Nb2S 4(NCS)5(dppm)2(dmf)] · 4 DMF (11), [Cu3NbS3Br(PPh3)3(dmf) 3]Br · [CuBr(PPh3)3] · PPh3 · OPPh3 · 3 DMF (12), [Cu3NbS3Cl2(PPh3) 3(dmf)2] · 1.5 DMF (13), (NEt4)[Cu3NbSe3Cl3(dmf)3] (14), [Cu6Nb2Se6O2(PMe3) 6] (15).

Application of 1317-39-1, Name is Copper(I) oxide, Application of 1317-39-1, molecular formula is Cu2O. In a article，once mentioned of Application of 1317-39-1

The photoelectrochemical properties of electrodeposited Cu2O in aqueous solutions were investigated. The material showed long term stability under illumination at negative potentials. The diffusion length of electrons in the as-deposited material was of the order of 10-100 nm. We did not observe photocathodic reduction of water. The efficiencies for the reduction of oxygen and the methylviologen cation at these electrodes were surprisingly high. This suggests that, in conjunction with a suitable redox system, electrodeposited Cu2O could be a promising material as a p-type photoelectrode in an electrochemical photovoltaic cell.

The synthesis and crystal structure elucidation of two novel polymeric copper(II) complexes has led us to propose a mechanism for the formation of 2-picolinic acid (pic) from di-2-pyridyl ketone (dpk) and benzoic acid from acetophenone. During studies into the interaction of copper ions with the dpk-acetophenone system, two complexes Na2(NCS)2(H 2O)[Cu(pic)2] (1) and Na2(H2O) 2[Cu(pic)2(NCS)2] (2) which contain pic coordinated to copper were isolated. The occurrence of (1) and (2) has led us to consider the Baeyer-Villiger rearrangement as a possible mechanism for the formation of (1) and (2).

We present an energy band model and a method for filling p-type CuSCN in n-type porous TiO2 film. The energy band model is based on the interface energy levels between TiO2/CuSCN heterojunction and the aqueous electrolyte. The whole deposition process is divided into three stages: the uniform nucleation on the internal surface at positive potential, the crystal growth with the cathodic potential shifting negatively and the thermal activated growth at constant potential. This was demonstrated by the electrochemical experiment combining the hydrothermal process. It was found that the obtained TiO2/CuSCN heterojunction exhibited good rectification characteristics, indicating that an intimate electrical contact was formed between the large internal surface of TiO2 film and CuSCN. This novel hydrothermal-electrochemical method may be valuable for fabricating extremely thin absorber (eta)-solar cells and other semiconductor devices.

Reaction of copper(I) thiocyanate and triphenylphosphane with the bidentate Schiff base N,N?-bis(trans-2-nitrocinnamaldehyde)ethylenediamine {Nca2en, (1); systematic name (1E,1?E,2E,2?E)-N,N?-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]}, C20H18N4O4, in a 1:1:1 molar ratio in acetonitrile resulted in the formation of the complex {(1E,1?E,2E,2?E)-N,N?-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]-kappa2 N,N?}(thiocyanato-kappaN)(triphenylphosphane-kappaP)copper(I)], [Cu(NCS)(C20H18N4O4)(C18H15P)] or [Cu(NCS)(Nca2en)(PPh3)], (2). The Schiff base and copper(I) complex have been characterized by elemental analyses, IR, electronic and 1H NMR spectroscopy, and X-ray crystallography [from synchrotron data for (1)]. The molecule of (1) lies on a crystallographic inversion centre, with a trans conformation for the ethylenediamine unit, and displays significant twists from coplanarity of its nitro group, aromatic ring, conjugated chain and especially ethylenediamine segments. It acts as a bidentate ligand coordinating via the imine N atoms to the CuI atom in complex (2), in which the ethylenediamine unit necessarily adopts a somewhat flattened gauche conformation, resulting in a rather bowed shape overall for the ligand. The NCS- ligand is coordinated through its N atom. The geometry around the CuI atom is distorted tetrahedral, with a small N-Cu-N bite angle of 81.56(12) and an enlarged opposite angle of 117.29(9) for SCN-Cu-P. Comparisons are made with the analogous Schiff base having no nitro substituents and with metal complexes of both ligands.

The versatile coordination behavior of the PNP ligands 1A (2,6-bis[(di-tert-butylphosphino)methyl]pyridine) and 1B (2,6- bis[(diphenylphosphino)methyl]pyridine) to CuI is described, whereby a hemilabile interaction of the pyridine N-donor atom to the copper center resulted in a rare T-shaped complex with 1A, while with 1B also a tetracoordinated species could be isolated. Theoretical calculations support the weak interaction of the pyridine N donor in 1A with the Cu center.

Diabetes is one of the most common disorders that substantially contributes to an increase in global health burden. As a metabolic disorder, diabetes is associated with various medical conditions and diseases such as obesity, hypertension, cardiovascular diseases, and atherosclerosis. In this review, we cover the scientific studies on sodium/glucose cotransporter (SGLT) inhibitors published during the last decade. Our focus on providing an exhaustive overview of SGLT inhibitors enabled us to present their chemical classification for the first time.

The addition of Yb(OTf)3 (10 mol%) in a Rh2(OAc)4-catalyzed reaction of o-(methoxycarbonyl)-alpha-diazoacetophe-none with N-methylmaleimide in CH2Cl2 or in diethyl ether gave cycloadducts with high endo-selectivity (endo:exo = 95:5-96:4). The CuOTf (20 mol%)-or CuCl-Yb(OTf)3 (5 mol%)-catalyzed reaction also gave 1,3-dipolar cycloadducts in an endo-selective manner (endo:exo = 94:6). On the other hand, a reaction using only Rh2(OAc)4 (5 mol%) as the catalyst in benzene under reflux gave cycloadducts with exo-selectivity (endo:exo = 11:89). The reaction of N-ethyland N-phenylmaleimides under the same conditions showed a similar tendency in terms of the stereoselectivity.
