Chiral phosphine ligands

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 13991-08-7, Name is 1,2-Bis(diphenylphosphino)benzene, molecular formula is C30H24P2.

A series of homoleptic copper(I), silver(I), and gold(I) complexes of two bisphosphine ligands {1,2-bis(diphenylphosphino)benzene, dppb; bis[2-(diphenylphosphino)phenyl]ether, POP} have been prepared. Whilst all three [M(dppb)2]BF4 complexes are tetracoordinate, this geometry is found only for the silver(I) complex with POP. Instead, [Cu(POP)2]+ and [Au(POP)2]+ adopt a trigonal coordination geometry with an uncoordinated phosphorus atom. A close inspection of the P-M bond lengths reveals an interesting trend. From the copper to silver and gold complexes, a substantial elongation is found. On the other hand, from the silver to gold compounds, a decrease in the M-P bond length is found. Indeed, gold(I) has a smaller van der Waals radius than silver(I) as a result of its peculiar relativistic effects. Electrochemical investigations revealed two oxidation processes for all of the [M(dppb)2]BF 4 and [M(POP)2]BF4 complexes. The first oxidation is likely metal-centered, whereas the second one corresponds to ligand-centered processes in all cases. The emission properties of these compounds in solution, in frozen rigid matrices at 77 K, and in the solid state at room temperature have been systematically investigated. Although all of them are weak emitters in solution, remarkably high emission quantum yields were found in the solid state, in particular for [Cu(dppb)2]BF4 and [Ag(dppb)2]BF4. Finally, these two compounds were used for the fabrication of light-emitting devices. Interestingly, both the copper(I) and the silver(I) complex afford quite broad electroluminescence spectra with white light emission. Copper(I), silver(I), and gold(I) [M(PP) 2]BF4 complexes have been prepared from two bisphosphine ligands, namely, 1,2-bis(diphenylphosphino)benzene (dppb) and bis[2-(diphenylphosphino)phenyl]ether (POP). Their electronic properties have been systematically investigated and rationalized as a combination of steric and electronic effects as well as by differences in their coordination geometries.

Efficient, phosphine-directed ortho C?H borylation of arylphosphine derivatives was achieved using Ru catalysts for the first time. The reaction is applicable to various tertiary arylphosphine and arylphosphinite derivatives to give (o-borylaryl)phosphorus compounds in high yields. This reaction enables easy access to a variety of functionalized phosphine ligands and ambiphilic phosphine boronate compounds, thus realizing a new late-stage modification of phosphorus compounds.

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.

A series of mononuclear Cu(I)-halide complexes, [CuX(PPh3)2(L)] (X=Cl-, Br-, I-; PPh3Combining double low linetriphenylphosphine; LCombining double low linepyridine (py), isoquinoline (iq), 1,6-naphthyridine (nap)), were synthesized. The emission color of [CuX(PPh3)2(L)] varies from blue to red by changing the L ligands and the halide ions, and all the complexes exhibit high emission quantum yields (0.16-0.99) in the crystals. The emission studies revealed that the emissive states of [CuX(PPh3)2(L)] differ depending on the L ligand. Complexes [CuX(PPh3)2(py)] and [CuX(PPh3)2(nap)] mainly emit from the singlet metal-to-ligand charge transfer mixed with the halide-to-ligand charge transfer (1(M+X)LCT) state at room temperature. In contrast, emissions from [CuX(PPh3)2(iq)] at room temperature originate from both 3(M+X)LCT and 3 pi pi?states. These results indicate that N-heteroaromatic ligands play an important role in the emission properties of mononuclear Cu(I)-halide complexes.
