Structure and reactivity of [(L¡¤Pd)n¡¤(1,5-cyclooctadiene)] (n = 1-2) complexes bearing biaryl phosphine ligands

The structure of the stable Pd(0) precatalyst [(1,5-cyclooctadiene)(L¡¤Pd)2] (L = AdBrettPhos) for the Pd-catalyzed fluorination of aryl triflates has been further studied by solid state NMR and X-ray cystrallography of the analogous N-phenylmaleimide complex. The reactivity of this complex with CDCl3 to form a dearomatized complex is also presented. In addition, studies suggest that related bulky biaryl phosphine ligands form similar complexes, although the smaller ligand BrettPhos forms a monomeric [(1,5-cyclooctadiene)(L¡¤Pd)] species instead.

Oligophosphine-thiocyanate Copper(I) and Silver(I) Complexes and Their Borane Derivatives Showing Delayed Fluorescence

The series of chelating phosphine ligands, which contain bidentate P2 (bis[(2-diphenylphosphino)phenyl] ether, DPEphos; 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene, Xantphos; 1,2-bis(diphenylphosphino)benzene, dppb), tridentate P3 (bis(2-diphenylphosphinophenyl)phenylphosphine), and tetradentate P4 (tris(2-diphenylphosphino)phenylphosphine) ligands, was used for the preparation of the corresponding dinuclear [M(mu2-SCN)P2]2 (M = Cu, 1, 3, 5; M = Ag, 2, 4, 6) and mononuclear [CuNCS(P3/P4)] (7, 9) and [AgSCN(P3/P4)] (8, 10) complexes. The reactions of P4 with silver salts in a 1:2 molar ratio produce tetranuclear clusters [Ag2(mu3-SCN)(t-SCN)(P4)]2 (11) and [Ag2(mu3-SCN)(P4)]22+ (12). Complexes 7-11 bearing terminally coordinated SCN ligands were efficiently converted into derivatives 13-17 with the weakly coordinating -SCN:B(C6F5)3 isothiocyanatoborate ligand. Compounds 1 and 5-17 exhibit thermally activated delayed fluorescence (TADF) behavior in the solid state. The excited states of thiocyanate species are dominated by the ligand to ligand SCN ? pi(phosphine) charge transfer transitions mixed with a variable contribution of MLCT. The boronation of SCN groups changes the nature of both the S1 and T1 states to (L + M)LCT d,p(M, P) ? pi(phosphine). The localization of the excited states on the aromatic systems of the phosphine ligands determines a wide range of luminescence energies achieved for the title complexes (lambdaem varies from 448 nm for 1 to 630 nm for 10c). The emission of compounds 10 and 15, based on the P4 ligand, strongly depends on the solid-state packing (lambdaem = 505 and 625 nm for two crystalline forms of 15), which affects structural reorganizations accompanying the formation of electronically excited states.

Seven copper (I) complexes of diphosphine ligands and N^N ligands: Syntheses, structural characterizations and spectroscopic properties

The reactions of diphosphine ligands and nitrogen-containing ligands with Cu(I) salts in the mixed solvents of methanol (MeOH) and dichloromethane (CH2Cl2) generated the corresponding complexes, {[Cu(dppbe)(Bphen)](ClO4)¡¤2CH3OH}n (1), {[Cu2(dppe)(dmp)2(CN)2]¡¤2CH3OH}n (2), {[Cu2(dppb)(dmp)2I2]¡¤2CH3OH}n (3), [Cu(POP)(C16H6N6)]I (4), {[Cu(POP)(C16H6N6)](SCN)}n (5), [Cu(xantphos)(bpy)](ClO4) (6) and {[Cu(xantphos)(bpy)](CF3SO3)}n (7) {dppbe = 1,2-bis(diphenylphosphanyl)benzene, dppe = 1,2-bis(diphenylphosphino)ethane; dppb = 1,4-bis(diphenylphosphino)butane, POP = bis[2-(diphenylphosphino)phenyl]ether, xantphos = 4,5-bis (diphenylphosphio)-9,9-dimethylxanthene, Bphen = 4,7-diphenyl-1,10-phenanthroline, dmp = 2,9-dimethyl-1,10-phenanthroline, C16H6N6 = [2,3-f]-pyrazino-[1,10]phenanthroline-2,3-dicarbonitrile, bpy = 2,2?-bipyridine}. These complexes were all characterized by single-crystal X-ray crystallography, elemental analysis, IR, 1H NMR spectroscopy, luminescence and THz spectroscopy. Complexes 1 and 2 consist of 1D infinite zigzag chain structures which are linked by hydrogen bonds, while complexes 3, 5 and 7 have 2D topological architectures which are connected by hydrogen bonds, complex 4 has an annular structure and complex 6 is a mononuclear structure. The types of hydrogen bonds, choice of solvents and coordination modes of the ligands are of importance in defining the structural and topological features of the resulting networks. Furthermore, complexes 1?7 exhibit interesting luminescence in the solid state at room temperature. Complexes 1?3 can act as yellow luminophores, complex 4 acts as a red luminophore, complex 5 acts as an orange luminophore and complexes 6?7 act as green luminophores. Their terahertz spectra show more accurate characteristics of their structures.

Synthesis, properties and structures of eight-coordinate zirconium(IV) and hafnium(IV) halide complexes with phosphorus and arsenic ligands

Eight-coordinate [MX4(L-L)2] (M = Zr or Hf; X = Cl or Br; L-L =o-C6H4(PMe2)2 or o-C 6H4(AsMe2)2) were made by displacement of Me2S from [MX4(Me2S) 2] by three equivalents of L-L in CH2Cl2 solution, or from MX4 and L-L in anhydrous thf solution. The [MI 4(L-L)2] were made directly from reaction of MI 4 with the ligand in CH2Cl2 solution. The very moisture-sensitive complexes were characterised by IR, UV/Vis, and 1H and 31P NMR spectroscopy and microanalysis. Crystal structures of [ZrCl4{o-C6H4(AsMe2) 2}2], [ZrBr4{o-C6H 4(PMe2)2}2], [ZrI 4{o-C6H4(AsMe2)2} 2] and [HfI4{o-C6H4(AsMe 2)2}2] all show distorted dodecahedral structures. Surprisingly, unlike the corresponding Ti(iv) systems, only the eight-coordinate complex was found in each system. In contrast, the ligand o-C6H4(PPh2)2 forms only six-coordinate complexes [MX4{o-C6H4(PPh 2)2}] which were fully characterised spectroscopically and analytically. Surprisingly the tripodal triarsine, MeC(CH2AsMe 2)3, also produces eight-coordinate [MX 4{MeC(CH2AsMe2)3}2] in which the triarsines bind as bidentates in a distorted dodecahedral structure. There is no evidence for seven-coordination as found in some thioether systems.

Taking TiF4 complexes to extremes – The first examples with phosphine co-ligands

The first soft donor adducts of TiF4, [TiF 4(diphosphine)] (diphosphine = o-C6H4(PMe 2)2, R2P(CH2)2PR 2, R = Me or Et) have been prepared from [TiF4(MeCN) 2] and the diphosphines in rigorously anhydrous CH2Cl 2, as extremely moisture sensitive yellow solids, and characterised by multinuclear NMR (1H, 31P, 19F), IR and UV/vis spectroscopy. The crystal structure of [TiF4{Et 2P(CH2)2PEt2}] has been determined and shows a distorted six-coordinate geometry with disparate Ti-F transF and Ti-FtransP distances and long Ti-P bonds. Weaker soft donor ligands including Ph3P, Ph2P(CH 2)2PPh2, o-C6H4(PPh 2)2, Ph2As(CH2)2AsPh 2, o-C6H4(AsMe2)2 and iPrS(CH2)2SiPr do not form stable complexes with TiF4, although surprisingly, fluorotitanate(IV) salts of the previously unknown doubly protonated ligand cations [LH 2][Ti4F18] (L = o-C6H 4(PPh2)2, o-C6H 4(AsMe2)2 and iPrS(CH 2)2SiPr) are formed in some cases as minor by-products. The structure of [o-C6H4(PPh 2H)2][Ti4F18] shows the first authenticated example of a diprotonated o-phenylene-diphosphine. The synthesis and full spectroscopic characterisation are reported for a range of TiF 4 adducts with hard N- or O-donor ligands for comparison purposes, along with crystal structures of [TiF4(thf)2], [TiF 4(Ph3EO)2]¡¤2CH2Cl 2 (E = P or As), and [TiF4(bipy)].

Total synthesis of 4-epi-atpenin A5 as a potent nematode complex II inhibitor

It is clear that atpenins and their analogs are useful chemical tools for elucidation of complex II functionality and that they could act as lead compounds for the development of novel helminth complex II-specific inhibitors. Recently, we discovered 4-epi-atpenin A5 as a potent nematode complex II inhibitor during our SAR studies of atpenin A5. This result led us to embark on a concise total synthesis of 4-epi-atpenin A5. In this study, we describe the total synthesis of 4-epi-atpenin A5. Importantly, this was more concise and practical synthesis than our previous total synthesis of atpenin A5.
