Electric Literature of 166330-10-5, An article , which mentions 166330-10-5, molecular formula is C36H28OP2. The compound – (Oxybis(2,1-phenylene))bis(diphenylphosphine) played an important role in people’s production and life.
Five mononuclear copper(I) complexes and one dinuclear silver(I) phosphine complex containing the bispyridylpyrrole ligand were synthesized and structurally characterized. Treatment of CuCl and the deprotonated bispyridylpyrrole ligand with bis(phosphine) ligands afforded the copper(I) complexes [(PDPH)Cu(XANTPhos)] (1), [(PDPH)Cu(DPEPhos)] (2), [(PDPBr)Cu(XANTPhos)] (3) and [(PDPBr)Cu(DPEPhos)] (4), while addition of two equivalences of PPh3 gave [(PDPBr)Cu(PPh3)2] (5), where PDPH- = 2,5-bis(2-pyridyl)pyrrole, PDPBr- = 2,5-bis(6?-bromo-2?-pyridyl)-pyrrole, XANTPhos = 9,9-di-methyl-4,5-bis(diphenylphosphino)xanthene, DPEPhos = oxydi-2,1-phenylene)bis-diphenylphosphine. Reaction of PDPBr- with AgOTf and DPEPhos yielded the dinuclear silver(I) complex [(PDPBr)Ag2(DPEPhos)](OTf) (6). All of these complexes were fully characterized on the basis of IR spectra, 1H and 31P NMR spectra, elements analysis, UV-Vis spectra and X-ray single crystal diffraction analysis. The photophysical properties of these complexes were also studied.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 166330-10-5, help many people in the next few years., Electric Literature of 166330-10-5
