Diphenyl complex with

PtPh2(SMe2)2 reacts with (2-ClC6H4)GH=NGH2GH2NMe2 to produce a monophenylplatinum complex having a 6, iV,7V-tridentate ligand (659, Equation (139)). An intermediate diphenyl complex with the bidentate ligand 658... [Pg.535]

Radical cyclization to triple bonds is used as the key step for the synthesis of oxygen heterocycles. This methodology can benefit from a Lewis acid, such as aluminum fns(2,6-diphenyl phenoxide) (ATPH), which forms a complex with the... [Pg.140]

Suga and Ibata [44] prepared binaphtyldiimine derivatives 36 (Scheme 19) affording 98% ee as best selectivity for the transformation of 1,1-diphenyl-ethylene with Z-menthyl diazoacetate. The authors performed PM3 calculations and proposed an optimized structure of the copper complex to explain the high enantioselectivity observed with 1,1-disubstituted olefins. [Pg.108]

A stopped flow technique coupled with spectrophotometric analysis of the iron (II) complex formed has been used to investigate - the reactions of some organic complexes of iron(III) with the ion Fe ". The iron(III) was complexed with 1,10-phenanthroline, various substituted 1,10-phenanthrolines (5-methyl-, 5-nitro-, 5-chloro-, 5-phenyl-, 5,6-dimethyl-, 4,7-diphenyl-, and 3,4,7,8-tetramethyl-) and 2,2 -dipyridine, 4,4 -dimethyl-2,2 -dipyridine, and 2,2, 2"-tripyridine. The wavelengths used for the analysis lay in the region 500-552 m/i. [Pg.108]

A review10 with eight references describes the photochemical reactions of the binuclear palladium(0) complex [Pd2(dppm)3] (dppm = bis(diphenyl)phosphinomethane) with organic halides. [Pg.557]

The zinc complexes with diphenyl-2-pyridylmethane, ZnL2Cl2 and ZnL2Br2, have been characterized by IR spectroscopy and conductivity measurements.107 The [(pyridyl)2P(NSi Mc3)2] ligand forms an aminoiminophosphoranate complex with zinc which structural characterization shows to be four-coordinate bound to two pyridyl and two amide nitrogen donors (3).108... [Pg.1154]

Bloodworth, A. J., et al., J. Chem. Soc., Perkin Trans. 1, 1983, 471-473 Attempted thermal dehydration of benzeneseleninic acid, formed by oxidation of diphenyl diselenide with hydrogen peroxide, gave a solid which exploded at 53-55°C. The solid may have been the complex of the acid with hydrogen peroxide. [Pg.1633]

Iridium(III) hydride forms complexes with DIOP, BDPP (2,4-bis(diphenyl-phosphino)pentane), NORPHOS, and BINAP ligands to produce amines in 11 -80% ee.679 Similar modest results are obtained in the reduction of N-arylketimines with an iridium(HI) complex with (2S,3 S) -C HIRA PHOS as the chiral ligand.680 The indium complexes with chiral phosphinodihydrooxazoles catalyze the enantioselective hydrogenation of imines in supercritical carbon dioxide with up to 80% ee, but generally lower ee values are observed in... [Pg.119]

More recently, the El and electrospray ionization (ESI) mass spectra of 2,5-diaryl- and 2-arylamino-5-aryl-l,3,4-oxadiazoles, as well as their complexes with copper cations, were studied. Under ESI conditions, loss of NH3 and HNCO, from complexes of 2,5-diphenyl-l,3,4-oxadiazole, 2,5-bis(2-pyridyl)-l,3,4-oxadiazole, or 2,5-bis(4-pyridyl)-1,3,4-oxadiazole with copper cation, was observed <2004JMP272>. An unusual elimination of isocyanic acid was found in fragmentation of some protonated 2,5-diaryl derivatives <2002RCM390>. [Pg.403]

An excess of l-chloro-3-iodopropane must be employed to compete effectively with the diphenyl sulfide for complexation with silver fluoroborate. [Pg.85]

A rather complex mixture of products is obtained from the reaction of benzyl-idenetriphenylphosphorane and CS2.48 The major product from the reaction of diphenyl disulphide with methylenetriphenylphosphorane is tris(phenylthio)-methane (44) and only a trace of the insertion product bis(phenylthio)methane is isolated.49 Presumably the salt (45) is deprotonated before it can react with the phenylthioate anion (Scheme 12). a-Thiocarbonyl-stabilized ylides (46) are obtained from the reaction of ylides with S-alkyl thiolcarboxylates.50... [Pg.186]

The square-planar geometry (with slight tetrahedral distortion) of these derivatives can be proved by that of the related Rh(I) complex with 2,2/-bis [o-(diphenylphosphine)benzylidene]amine -6,6/-dimethyl-diphenyl, [Rh(PPNN)]+, Figure 23.26... [Pg.463]

Two five-coordinate Mn =0 complexes with N2O2 tetradentate ligands Ph4P[MnOL] (L= 1,2-bis(2-methyl-2-oxypropanamido)benzene and 1,2-bis(2,2-diphenyl-2-hydroxyethanamido)benzene) have been prepared and structurally characterized (12) and (13), respectively.These complexes and the 0x0 complexes discussed in the next section may have utility in oxo-transfer reactions to organic substrates such as olefins and ethers. [Pg.10]
