Gundogan and published by . This book was released on 2014 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aryl group can indeed be transferred into platinum metal having strong phosphine ligand provided that Cu(I) salts used as catalyst. Different ligands were tested to investigate the scope of the reaction, a library of monosubstituted, symmetrically disubstituted and asymmetrically disubstituted platinum complexes were prepared. Basic photophysical properties i.e. ground-state absorption, steady-state emission in both air-saturated and argon purged solutions were studied. Finally, the novel carbon-platinum bond formation reaction was used to synthesize a series of platinum complexes in which 2,1,3-benzothiadiazole was ligated with various electron-rich systems was connected via platinum metal. Extensive photophysical and electrochemical investigation was conducted on these novel platinum complexes.

Book Synthesis Characterization and Reactivity of Low Valent Technetium Phosphine Complexes

Download or read book Synthesis Characterization and Reactivity of Low Valent Technetium Phosphine Complexes written by Evan Freiberg and published by . This book was released on 2001 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 1. The chemistry of the metal-metal multiply bonded Tc2(II, II) core has been investigated with bis(diphenylphosphino)methane (dppm). The parent complex, Tc2Cl4(dppm)2, has been prepared from the reaction of Tc2C14(PEt3)4 with dppm. The reactivity of Tc2Cl4(dppm)2 with tert-butyl isocyanide has been studied and a neutral 1:1 adduct, Tc2Cl4(dppm)2CNBut, a cationic 1:2 adduct, [Tc2Cl3(dppm)4(CNBut)2](PF6), and a [mu]-iminyl complex, [Tc2Cl3(dppm)2(CNBut)2CNHBul(PF6), have been prepared. The parent compound and its reaction products have been characterized via a combination of spectroscopic techniques and single crystal X-ray crystallography. The metal-metal bonded ditechnetium bis(dppm) motif is retained in the reaction products. Chapter 2. The reduction of ammonium pertechnetate with bis(diphenylphosphino)methane (dppm), and with diphenyl-2-pyridyl phosphine (Ph2Ppy), has been investigated. The neutral Tc(II) complex, TcCl2(dppm)2, has been isolated from the reaction of (NH4)[TcO4] with excess dppm in refluxing EtOH/HCl. Chemical oxidation with ferricinium hexafluorophosphate results in formation of the cationic Tc(III) analogue, [TcCl2(dppm)2](PF6). The dppm ligands adopt the chelating bonding mode in both complexes, resulting in strained four member metallocycles. With excess PhPpy, the reduction of (NH4)[TcO4] in refluxing EtOH/HCl yields a complex with one chelating Ph2Ppy ligand and one unidentate Ph2Ppy ligand, TcCl3(Ph2Ppy-P, N)(Ph2Ppy-P).

Abstract: Abstract of thesis entitled SYNTHESIS, STRUCTURES AND SPECTROSCOPIC PROPERTIES OF PRIMARY AND SECONDARY PHOSPHINE COMPLEXES OF IRON, RUTHENIUM AND OSMIUM PORPHYRINS Submitted by XIE JIN For the degree of Doctor of Philosophy at The University of Hong Kong in Oct 2007 Primary and secondary phosphine complexes of transition metals are of fundamental importance in metal-mediated P-H bond functionalization, phosphido/phosphinidene formation, and have applications in materials science. This thesis mainly describes the first isolation of primary and secondary phosphine complexes of a metalloporphyrin, along with their spectral, structural, and redox properties. The reactivity of primary and secondary phosphines coordinated to metalloporphyrins, particularly their hydrophosphination reactions with C=C bonds, is included. Investigations on the attempted approach to metal primary phosphine complexes bearing a pentapyridyl ligand (PY5) are also included. Ruthenium and osmium porphyrins form isolable complexes with primary and II secondary phosphines. Complexes [Ru (por)(PH Ph )] and n 3-n 2 II II [Os (por)(CO)(PH Ph )] (n = 1, 2) were prepared from reaction of [M (por)(CO)] n 3-n VI (M = Ru, Os) with excess PH Ph or PHPh . Reaction of [Os (por)O ] with PHPh 2 2 2 2 II mainly generated [Os (por){P(OH)Ph }(PHPh )], with concomitant formation of 2 2 II minor amounts of [Os (por){P(OH)Ph } ]. The bis-(primary phosphine) complex 2 2 II [Ru (F -tpp)(PH Ph)] is strikingly stable toward air and features reversible 20 2 2 +/0 Ru(II)/Ru(III) oxidation couple at E = 0.39 V vs Cp Fe . NMR spectrum 1/2 2 simulation revealed a strong coupling between the trans P nuclei in II 2 2 [Ru (por)(PH Ph ) ] (n = 1, 2; J ≈ 500 Hz). A J value of 467 Hz was directly n 3-n 2 PP PP 31 II obtained from the proton-decoupled P NMR spectrum of [Os (F - 20 tpp){P(OH)Ph }(PHPh )], which is much larger than that observed for the trans 2 2 phosphines in a non-porphyrin osmium phosphine complex. A one-pot synthesis of metal primary phosphine complexes from user-friendly O=PClR and PClR has been realized by treating these precursors with 2 2 II [Ru (por)(CO)] and LiAlH, leading to the isolation of primary alkylphosphine II complexes of ruthenium porphyrins, [Ru (por)(PH R) ] (por = ttp, 4-MeO-ttp, F -tpp; 2 2 20 t sec R = Ad, Bu, Bu), which are the first examples of primary alkylphosphine complexes of ruthenium. II Reactions of [Ru (F -tpp)(PH Ph ) ] (n = 1, 2) with CH =CHR (R = CO Et, 20 n 3-n 2 2 2 t II CN) in the presence of BuOK afforded [Ru (F -tpp){P(CH CH R) Ph } ] in high 20 2 2 n 3-n 2 yields. This is the first observation of alkene hydrophosphination by primary/secondary phosphines coordinated to a metalloporphyrin. The reactions of III [Fe (por)Cl] (por = F -tpp, 2,6-Cl tpp) with Na S O followed by treatment with 20 2 2 2 4 excess PH Ph, PHPh, or PH Ad led to the isolation of the first examples of iron 2 2 2 porphyrin complexes of primary and secondary phosphines, of which the primary phosphine complexes underwent partial dissociation in solutions at room temperature. Treatment of PY5 (or PY5-OH) with Ag(p-MeC H SO), AgNO, or 6 4 3 3 [Cu(MeCN) ]PF resulted in the isolation of [Ag (L) ]X (L = PY5 or PY5-OH, X = 4 6 2 2 2 - - I p-MeC H SO or NO ) and [Cu (PY5)(MeCN)]PF, which adopt two types of 6 4 3 3 6
