Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 13991-08-7, Name is 1,2-Bis(diphenylphosphino)benzene, name: 1,2-Bis(diphenylphosphino)benzene.

The complexes PtII(P-P)(CN)2 with P-P = 1,2-bis(diphenylphosphanyl)benzene (dppb) and 2,2?-bis(diphenylphosphanyl) -1,1?-binaphthyl (binap) were synthesised and characterised by elemental analysis, ESI MS and electronic spectroscopy. The structure of Pt(dppb)(CN) 2 was resolved by single-crystal X-ray diffraction. This compound consists of mononuclear PtII complexes with an almost planar PtP 2C2 coordination. While both complexes are not luminescent in solution, they show an emission in the solid state under ambient conditions. It is suggested that the luminescence of Pt(dppb)(CN)2 originates from a (PtII?dppb) metal-to-ligand charge transfer (MLCT) triplet with some dppb intraligand (IL) contribution. This assignment is confirmed by calculations which provide further insight into the excited state properties of the complex. In solution the phosphorescence is absent because the MLCT/IL state is deactivated to a non-emissive ligand field (LF) triplet, which is located at rather low energies owing to its distortion towards a tetrahedral structure. In the solid state this distortion is hindered. In the case of solid Pt(binap)(CN)2, the phosphorescence is apparently of the IL type as the pipi* triplet of the binaphthyl chromophore occurs at low energies. Again, in solution the phosphorescence is absent owing to the interference by a distorted LF state. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.

Unsymmetric di(heteroaryl) ethers were synthesized by the rhodium-catalyzed heteroaryl exchange reaction of heteroaryl aryl ethers and heteroaryl esters at equilibrium. Diverse unsymmetric di(heteroaryl) ethers containing five- and six-membered heteroarenes were obtained. Di(heteroaryl) ethers can be synthesized starting from diaryl ethers, because heteroaryl aryl ethers are obtained by the heteroaryl exchange reaction of diaryl ethers.

A rhodium complex catalyzed the conversion of the C-O bond of heteroaryl aryl ethers to the C-F bond. The reaction of (4-chlorophenylthio)pentafluorobenzene with heteroaryl aryl ethers provided heteroaryl fluorides and heteroaryl (4-chlorophenylthio)tetrafluorophenyl ethers; this involved the cleavage of a single heteroaryl C-O bond under equilibrium conditions. The reaction of heteroaryl aryl ethers with 2-fluorobenzothiazole in which two heteroaryl and aryl C-O bonds were cleaved provided heteroaryl fluorides and aryl fluorides. The reactions were applicable to five-membered and six-membered heteroaryl aryl ethers and also to diaryl ethers possessing one or two electron-withdrawing groups.

Treatment of Fe2(pdt)(CO)4(dppv) (1) with aryldiazonium salts affords the 34 e- adducts [Fe2(pdt) (nu-N2Ar)(CO)4(dppv)]+ (pdt2- = 1,3-propanedithiolate, dppv = cis-C2H2(PPh 2)2). Under some conditions, the same reaction gave substantial amounts of [1]+, the product of electron transfer. Consistent with the influence of electron transfer in the reactions of some electrophiles with Fe(I)Fe(I) dithiolates, the reaction of [Me3S 2]+ and Fe2(pdt)(CO)4(dppbz) was found to give [Fe2(pdt)(CO)4(dppbz)]+ as well as Me2S and Me2S2 (dppbz = 1,2- bis(diphenylphosphino)benzene).

The reactions of the soft diphosphines o-C6H 4(PMe2)2, Me2P(CH2) 2PMe2, Et2P(CH2)2PEt 2 or o-C6H4(PPh2)2 with NbF5 or TaF5 in anhydrous MeCN solution produce [MF 4(diphosphine)2][MF6] (M = Nb or Ta), which have been characterised by microanalysis, IR, 1H, 19F{1H}, 31P{1H} and 93Nb NMR spectroscopy. X-ray crystal structures are reported for the isomorphous [MF4{o-C6H4(PMe2)2} 2][MF6], which confirm the presence of eight-coordinate (distorted dodecahedral) cations. The corresponding reactions using o-C 6H4(AsMe2)2 produced [MF 4{o-C6H4(AsMe2)2} 2][MF6] which were similarly characterised, including by the X-ray structure of [NbF4{o-C6H4(AsMe 2)2}2][NbF6]. These are very rare examples of arsine complexes of high valent metal fluorides. The chloro complexes [NbCl4{o-C6H4(PMe2) 2}2]Cl, [TaCl4{o-C6H 4(PMe2)2}2][TaCl6], [NbCl4{Me2P(CH2)2PMe 2}2][NbCl6] and [MCl4{o-C 6H4(AsMe2)2}2][MCl 6] were prepared and their structural and spectroscopic properties compared with the fluoride analogues. Attempts to prepare diphosphine complexes of NbOF3 were unsuccessful, but the NbOCl3 complexes, [{{Me2P(CH2)2PMe2}NbOCl 3}2{mu-Me2P(CH2) 2PMe2}] and [{o-C6H4(PMe 2)2}NbOCl3(mu-O)NbCl3(CH 3CN){o-C6H4(PMe2)2}] were obtained. X-Ray structures are also reported for [NbCl4{o-C 6H4(PMe2)2}2]Cl, [NbCl4{o-C6H4(AsMe2) 2}2][NbCl5(OEt)], [NbCl4{o-C 6H4(PMe2)2}2][NbOCl 4(CH3CN)], [{{Me2P(CH2) 2PMe2}NbOCl3}2{mu-Me 2P(CH2)2PMe2}] and [{o-C 6H4(PMe2)2}NbOCl3(mu-O) NbCl3(CH3CN){o-C6H4(PMe 2)2}].

A document type is Review, introducing its new discovery.

Thermally activated delayed fluorescence (TADF) and TADF-organic light-emitting diodes (OLEDs) systems are being given increasing attention in research nowadays. Much more work has been done for organic-based materials in this field, but the use of TADF organometallic systems has also emerged in recent years. In particular, TADF-based gold compounds have not been particularly well-explored, with a higher number of examples of Au(I)-molecules and fewer for the higher oxidation state Au(III) derivatives. Nevertheless, the novelty and observed results deserve attention. A careful analysis has been performed in this review by classifying the reported compounds into two different groups regarding the oxidation state of the metal, and within each group, the ancillary ligands. Specific examples to illustrate their potential applications are included in the different section.

Rhenium(I) N-heterocyclic carbene complexes of the type [HNCH2CH2NHCRe(L-L)(CO)3]+ have been prepared, where L-L = 4,4?-dimethoxy-2,2?-bipyridine (2), 4,4?-bis(tert-butyl)-2,2?-bipyridine (3), 2,2?-bipyridine (4), 4,4?-dichloro-2,2?-bipyridine (5), 4,4?-bis(carbomethoxy)-2,2?-bipyridine (6), 5-phenyl-1,10-phenanthroline (7), and o-phenylenebis(diphenylphosphine) (8). The molecular structures of 4, 6, and 8 have been determined by X-ray analyses and show Re-C(carbene) bond distances of 2.171(7), 2.163(4), and 2.199(6) A, respectively. HF-SCF and MP2 calculations on the model compound [HNCH2CH2NHCRe(NHCHCHNH)-(CO)3]+ (4m) show that the HOMO is nonbonding d(Re) and the LUMO is mainly pi*(diimine) with partial pz(carbene) character. CIS calculations on the excited state of optimized 4m suggest that the lowest energy absorption originates from a HOMO to LUMO spin-forbidden transition. Complexes 2-7 are emissive at room temperature and 77 K. The room-temperature and 77 K luminescence data of 2-6 are consistent with emission from a 3-MLCT state. The nature of the emission of 7 at room temperature is also 3MLCT but changes to IL at 77 K. Complex 8 does not emit at room temperature, but at 77 K, the IL pi(pdpp) ? pi(pdpp) emission is observed. The combination of detailed spectroscopic studies and theoretical calculations reveal that the emitting state at room temperature is 3[d(Re) ? pi*-(diimine)], with the latter exhibiting partial sigma*(carbene) parentage. The excited-state energies and redox potentials can be tuned using diimine ligands with varying electron-donating/accepting abilities.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 1,2-Bis(diphenylphosphino)benzene, you can also check out more blogs about13991-08-7

The bidentate phosphine ligands bis(diphenylphosphino)acetylene and 1,4-bis(diphenylphosphino)benzene have been found effectively to stabilise polynuclear copper/chalcogenide/chalcogenolate cores, acting as intramolecular bridges between copper centres.
