Lopes, Cesar; Hakansson, Mikael; Jagner, Susan published the article 《Products of the reaction between copper(I) phenoxide and triphenylphosphine》. Keywords: crystal structure copper phenoxide phosphine complex; structure copper phenoxide phosphine dinuclear tetranuclear; copper phenolate phosphine complex preparation structure; phenoxide copper phosphine complex preparation structure.They researched the compound: Mesitylcopper(I)( cas:75732-01-3 ).Reference of Mesitylcopper(I). Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:75732-01-3) here.
Two phenolatocopper(I) derivatives, [Cu4(PPh3)4(OPh)4] (1) and [Cu2(PPh3)3(OPh)2] (2), were prepared by the addition of triphenylphosphine to copper(I) phenoxide, obtained from mesitylcopper(I) and phenol. Characterization by crystal structure determination showed 1 to be a tetramer with a cubane-type Cu4O4 core in which Cu-O distances range from 2.05(2)-2.26(2) Å. 2 Is a μ2-phenoxide dimer in which one copper(I) center is four-coordinated by two phenoxide and two triphenylphosphine ligands, while the other is coordinated by a single triphenylphosphine ligand and thus three-coordinated. Complex 1 crystallizes as the solvate [Cu4(PPh3)4(OPh)4]·(PhMe)2 in the monoclinic space group P21/c with a 14.822(7), b 23.160(4), c 28.193(6) Å, β 98.64(2)° at -90° and Z = 4; full-matrix least-squares refinement yielded R = 0.082 for 529 parameters and 3931 observed reflections. [Cu2(PPh3)3(OPh)2] (2) crystallizes in the triclinic space group P1̅ with a 13.948(4), b 16.846(2), c 12.480(3) Å, α 94.92(2), β 110.45(2), γ 95.96(2)° at -120° and Z = 2; full-matrix least-squares refinement yielded R = 0.063 for 328 parameters and 2507 observed reflections. The effect of increasing the PPh3:CuOPh ratio on the stability of the phenoxide is discussed in terms of the coordination geometry and consequent accessibility of the metal to small mols.
