A document type is Article, introducing its new discovery.

Ion-pair compounds of phenyl-substituted viologen dications with [M(mnt)2] dianions were prepared and characterized. (Benzyl viologen)[M(mnt)2] (M = Cu (1), Ni (2), Pt (3)) and (phenyl viologen)[Cu(mnt)2] (4) exhibited mixed-stack crystal structures, whereas (dinitrophenyl viologen)[Cu(mnt)2] (5) exhibited no pi-pi interactions. Magnetic susceptibility measurements revealed that 1 exhibits a ferromagnetic exchange interaction (Weiss constant theta = +0.9 K), possibly mediated by the diamagnetic cation. Antiferromagnetic interactions were observed for 4 (theta = -2.0 K) and 5 (theta = -2.9 K), whereas 2 and 3 were diamagnetic. Absorption bands assignable to charge transfer were observed in the mixed-stack salts in the visible to near-infrared region.

Treatment of the chloro-bridged dinuclear complex [Pd{3,4-(MeO)2C6H2C(H){double bond, long}N(Cy)-C6,N}(mu-Cl)]2 (1) with homobidentate [P,P], [As,As], [N,N], and heterobidentate [P,As], [P,N] ligands in a 1:1 molar ratio gave the dinuclear complexes [{Pd[3,4-(MeO)2C6H2C(H){double bond, long}N(Cy)-C6,N](Cl)}2{mu-L}] (L = Ph2PC4H6(NH)CH2PPh2 (2); Ph2As(CH2)2AsPh2 (3); 1,3-(NH2CH2)2C6H4 (4); Ph2P(CH2)2AsPh2 (5); Ph2P(CH2)2NH2 (6)), with the bidentate ligands bridging the two cyclometallated fragments. The reaction with the homobidentate ligands in a 1:2 molar ratio in the presence of NaClO4 afforded the mononuclear compounds [[Pd{3,4-(MeO)2C6H2C(H){double bond, long}N(Cy)-C6,N}{L-P,P}][ClO4] (L = Ph2PC4H6(NH)CH2PPh2 (7); (o-Tol)2P(CH2)2P(o-Tol)2 (8)), [Pd{3,4-(MeO)2C6H2C(H){double bond, long}N(Cy)-C6,N}{Ph2As(CH2)2AsPh2-As,As}][ClO4] (9) and [Pd{3,4-(MeO)2C6H2C(H){double bond, long}N(Cy)-C6,N}{L-N,N}][ClO4] (L = NH2(CH2)3NH2 (10); NH2(C6H8)CH2(C6H8)NH2 (11); 1,3-(NH2CH2)2C6H4 (12); 1,3-(NH2)2C5H3N (13); NH2(C6H4)O(C6H4)NH2 (14); NMe2(CH2)2NMe2 (15)), in which the chloro ligands are absent and the bidentate ligands are chelated to the palladium atom. Reaction of 1 with Ph2P(CH2)2AsPh2 in 1:2 molar ratio in acetone in the presence of NH4PF6 afforded the analogous mononuclear compound [Pd{3,4-(MeO)2C6H2C(H){double bond, long}N(Cy)-C6,N}{Ph2P(CH2)2AsPh2-P,As}][PF6] (16); whereas reaction with Ph2P(CH2)3NH2 gave [Pd{3,4-(MeO)2C6H2C(H){double bond, long}N(Cy)-C6,N}{Ph2P(CH2)3N(C{double bond, long}Me2)-P,N}][PF6] (17), derived from intermolecular condensation between the aminophosphine and acetone. Condensation of the NH2 group was precluded by change of solvent, using dichloromethane. Iminophoshines also reacted with 1 in 1:2 molar ratio in acetone to give a new series of mononuclear cyclometallated complexes: [Pd{3,4-(MeO)2C6H2C(H){double bond, long}N(Cy)-C6,N}{L-P,N}][ClO4] (L = Ph2PC6H4C(H){double bond, long}NCy (20); Ph2PC6H4C(H){double bond, long}NC(CH3)3 (21); Ph2PC6H4C(H){double bond, long}NNMe2 (22); Ph2PC6H4C(H){double bond, long}NNHMe (23); Ph2PC6H4C(H){double bond, long}NNHPh (24)). Analogous complexes with a stable P,O-chelate were obtained using bidentate [P,O] donor ligands: [Pd{3,4-(MeO)2C6H2C(H){double bond, long}N(Cy)-C6,N}{L-P,O}][Cl] (L = 2-(Ph2P)C6H4CHO (25); Ph2PN(Me)C({double bond, long}O)Me (26)).

Herein we present a structure-property relationship study of thirteen cationic iridium(iii) complexes of the form of [Ir(C^N)2(P^P)]PF6 in both solution and the solid state through systematic evaluation of six bisphosphine (P^P) ligands (xantphos, dpephos, dppe, Dppe, nixantphos and isopropxantphos). All of the complexes are sky-blue emissive, but their photoluminescence quantum yields (PhiPL) are generally low. However, strong and long-lived blue luminescence (lambdaem = 471 nm; PhiPL = 52%; taue = 13.5 mus) can be obtained by combining the reduced bite angle of the 1,2-bis-diphenylphosphinoethene (dppe) chelate with the bulky 2-(4,6-difluorophenyl)-4-mesitylpyridinato (dFmesppy) cyclometalating ligand. To the best of our knowledge this is the highest PhiPL and the longest taue reported for cyclometalated iridium(iii) complexes bearing bisphosphine ligands. Light-emitting electrochemical cells (LEECs) were fabricated using lead complexes from this study, however due in part to the irreversible electrochemistry, no functional LEEC was achieved. Organic light-emitting diodes were successfully fabricated but only attained maximum external quantum efficiencies of 0.25%.

The incredible bulk: The first palladium-catalyzed amidation of five-membered heterocyclic bromides with multiple heteroatoms was achieved using the Pd/1 catalyst system. N-Arylated imidazoles, pyrazoles, thiazoles, pyrroles, and thiophenes were synthesized in moderate to excellent yield. Experimental results and DFT calculations point to the need for an electron-rich and sterically demanding biaryl phosphine ligand to promote these difficult reactions. Copyright

A series of palladium(II) and platinum(II) complexes Cl2M(P-N-O) (M = Pd, Pt) with bidentate Schiff bases (P-N-O) from 2-(diphenylphosphino) benzaldehyde and a-amino acid esters has been synthesized, using PdCl 2 or K[PtCl3(C2H4)], respectively. Abstraction of chloride from Cl2M(P-N-O) (using AgBF4) has afforded the cationic complexes [(P-N-O)M(Cl)]+BF4- in which the Schiff bases function as tridentate ligands with coordination of the ester group. The structures of Cl2Pd(Ph2PC 6H4C(H)=N-CH2CO2Et) and of [(Cl)Pd(Ph2PC6H4C(H)=NC( H)(CH 2CH=CH2)CO2Me)]+BF4 – have been determined by X-ray diffraction. Complexes (L)MCl 2 and [(L)MCl]+BF4 (M = Pd, Pt) have also been prepared with the reduced Schiff base Ph2PC6H 4CH2NHC(H)(CH2Ph)CO2Me.

We studied the luminescence properties of copper(i) complexes containing bis[2-(diphenylphosphino)phenyl]ether (DPEphos), [Cu(DPEphos)(CH 3CN)]PF6 (1), [Cu(DPEphos)2]PF6 (2), and copper(i) complexes with 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (xantphos), [Cu(xantphos)(CH3CN)2]PF6 (3), [Cu(xantphos)2]PF6 (4) in the solid state. The metal-free xantphos ligand shows weak phosphorescent emission at around 455 nm with an emission lifetime in the sub-microsecond range in the solid state at room temperature. When xantphos forms complex 4, it results in a nearly 4-fold increase in the emission quantum yield and emission lifetime, with a small shift in the emission maximum. In contrast, no such enhancement in the luminescence or increment in the emission lifetime was observed in complexes 1-3. The X-ray structural analysis of complexes 1-4 reveals a large vacant space in complexes 1-3 and in contrast, close packing of the ligands in complex 4 around the metal center. This indicates that the decrease in the free-space around the metal center results in a decrease in the geometric relaxation, suppressing the excited-state deactivation pathway.

Synthetic Route of 166330-10-5. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 166330-10-5, Name is (Oxybis(2,1-phenylene))bis(diphenylphosphine). In a document type is Article, introducing its new discovery.

The preparation of heteroleptic Cu complexes from various 2,9-disubstituted-1,10-phenanthrolines (phen) and different bis-phosphine (PP) ligands was investigated. These heteroleptic complexes are found to be stable in CH2Cl2 solutions and no detectable ligand exchange reactions could be detected. The results also show that the CuI-mediated threading of all the bis-phosphine ligands through the macrocycle is effective. The X-ray crystal structure analysis of BF4 proves the threading of the POP moiety through the macrocyclic phenanthroline ligand. The intramolecular face-to-face p p interaction between one phenyl ring of the POP ligand and the phenanthroline moiety induces a significant rocking of the POP ligand. The results also show that formation of the homoleptic bisphenanthroline Cu complex is prevented by the macrocyclic nature of the phenanthroline ligand.
