Published: March 2004

AbstractPlatinum bisphosphine complexes bearing dichalcogen‐derivatised naphthalene, acenaphthene or phenanthrene ligands have been prepared by either oxidative addition to zero‐valent platinum species or from [PtCl2(PPhR2)] (R=Ph or Me) and the disodium or dilithium salts of the parent disulfur, diselenide or mixed S/Se species. The parent naphthalene, acenaphthene and phenanthrene chalcogen compounds were treated with either [Pt(PPh3)4] or [Pt(C2H4)(PMe3)2] (prepared in situ from [PtCl2(PMe3)2], ethene and sodium naphthalide or super hydride [LiBEt3H]) to give the appropriate platinum(II) species. The dilithium salts of 1,8‐E2‐naphthalene (E=S or Se) prepared in situ by reduction of the EE bond with [LiBEt3H] were treated with [PtCl2(PPh3)2] to give [Pt(1,8‐E2‐nap)(PPh3)2]. The tetraoxides [Pt(1,8‐(S(O)2)2‐nap)(PR3)2] (PR3=PPh3 or PMe2Ph) were prepared in a similar metathetical manner from the appropriate [PtCl2(PR3)] complexes and the disodium salt of naphthalene 1,8‐disulfinic acid (1,8‐(S(O)ONa)2‐nap). The X‐ray structures of selected examples reveal bidentate coordination with the naphthalene‐E2 unit hinged (111–137°) with respect to the coordination plane. The naphthalene ring suffers significant distortion from planarity.

AbstractThe synthesis, characterisation, and X‐ray structure of a new strained asymmetric diferrocene derivative (2) is reported. Compound 2 acts as a highly specific electrochemical and optical Mg2+ ion sensor, as revealed by spectroscopic and electrochemical techniques. Thus, in the presence of Mg2+, a new redox peak appears in the cyclic voltammogram (CV) that is anodically shifted compared to the E1/2 of the free receptor (ΔE1/2=340 mV). Diferrocene derivative 2 also gives a highly visual response upon addition of Mg2+, namely a change of colour from orange to deep purple. In addition, compound 2 does not show any significant sensing activity in the presence of Ca2+ or alkaline ions. On protonation, it is converted into the stable diferrocenylcarbenium salt 4, in which two different modes of stabilisation of the α‐carbocationic centre are clearly demonstrated by a combination of 1H NMR and 57Fe Mössbauer spectroscopic measurements. Finally, by a partial (chemical or electrochemical) oxidation, compound 2 forms the asymmetric mixed‐valence species 2+, which can be isolated as the solid salt 6 by using CF3SO3− as a counterion. This mixed‐valence species shows a fast intramolecular electron‐transfer process, as ascertained by several spectroscopic techniques.
Synthesis and Photochemistry of a New Class of Photocleavable Protein Cross‐linking Reagents
Authors: Milanesi Lilia , Reid Gavin D. , Beddard Godfrey S. , Hunter Christopher A. , Waltho Jonathan P. 
Published: March 2004

AbstractA new series of photocleavable protein cross‐linking reagents based on bis(maleimide) derivatives of diaryl disulfides have been synthesised. They have been functionalised with cysteine and transient absorption spectra for the photolysis reaction have been recorded by using the pump‐probe technique with a time resolution of 100 femtoseconds. Photolysis of the disulfide bond yields the corresponding thiyl radicals in less than a picosecond. There is a significant amount of geminate recombination, but some of the radicals escape the solvent cage and the quantum yield for photocleavage is 30 % in water.

AbstractThe deprotonated form of the ligands pyrazine‐2,3‐diselenol (pds) and pyrazine‐2,3‐dithiol (pdt) react with Cu(ClO4)2⋅6 H2O to form different CuIII complexes Na[CuIII(pds)2]⋅2 H2O (1), Li[CuIII(pds)2]⋅3 H2O (2), and Na[CuIII(pdt)2]⋅2 H2O (4) depending on the countercation compound used as deprotonating agent (NaOH, LiOH). Two other CuIII complexes were obtained by replacement of the alkali metal cations with tetrabutylammonium (TBA+), namely, TBA[CuIII(pds)2] (3), and TBA[CuIII(pdt)2] (5). All complexes were characterized by 1H and 13C NMR and IR spectroscopy, electronic absorption, elemental analysis, cyclic voltammetry (CV), and X‐ray crystallography. Electrical conductivity measurements on single crystals show that these salts exhibit insulating behavior. The crystal structure of these species revealed a lateral coordination capability of the N atoms of the pyrazine ring of both pds and pdt ligands towards the alkali metal ions, which leads to the build up of a net of coordinative bonds, hydrogen bonds, and contacts that result in the final 3D structure. Two parameters control the crystal engineering of the final 3D structures: the nature of the alkali metal countercation and the nature of the chalcogen atom (Se/S), which allow fine‐tuning of complex 3D crystal lattice. Density functional calculations were performed on the [Cu(pds)2] and [Cu(pdt)2] systems to investigate the electronic structure of the complexes and understand their electronic and electrochemical behavior by studying the frontier molecular orbitals. This study also reveals whether the redox processes take place on the ligands or on the metal center, a question under continuous discussion in the literature.
Ring‐Closure Reactions through Intramolecular Displacement of the Phenylselenonyl Group by Nitrogen Nucleophiles: A New Stereospecific Synthesis of N‐Tosyl and N‐Benzoyl‐1,3‐oxazolidin‐2‐ones from β‐Hydroxyalkyl Phenyl Selenides
Authors: Tiecco Marcello , Testaferri Lorenzo , Temperini Andrea , Bagnoli Luana , Marini Francesca , Santi Claudio 
Published: March 2004

AbstractA new and convenient method for the stereospecific synthesis of variously substituted 1,3‐oxazolidin‐2‐ones from the easily available β‐hydroxyalkyl phenyl selenides is presented. After transformation into the N‐tosyl or N‐benzoyl carbamates, the selenides were oxidized to the corresponding selenones. The key step of the process is the ring‐closure reaction, which occurs by stereospecific intramolecular nucleophilic substitution of the selenone group by the nitrogen atom of the carbamate. Enantiomerically pure 1,3‐oxazolidin‐2‐one derivatives can be easily prepared by using enantiomerically pure β‐hydroxyalkyl phenyl selenides as starting materials.
tBuP(NH2)2—A Reactive Synthon for the Synthesis of Molecular Imidophosphinates of Group 13 Metals

Published: March 2004

AbstractReactions of tBuP(NH2)2 with Group 13 trialkyls MR3 (M=Al, Ga, In; R=Me, tBu) were investigated in detail. According to variable‐temperature (VT) NMR investigations, the reaction proceeds stepwise with the initial formation of aminophosphane adducts, which subsequently react to give iminophosphorane adducts and finally the heterocyclic metallonitridophosphinates. BP86/TZVPP (DFT) calculations were performed to verify this reaction pathway, to elucidate the influence of the central Group 13 element on the stability of the reaction intermediates and the heterocycles, as well as to assess the thermodynamics of their formation. The relative stability of free and complexed aminophosphane RP(NH2)2 and iminophosphorane R(H2N)(H)PNH (adducts) with PIII and PV centers was studied in more detail with DFT and MP2 methods. In addition, the influence of the substituent R was investigated by variation of R from H to Me, tBu, F, and NH2. In general, the aminophosphane form was found to be favored for the free ligand, however, upon complexation with MR3 (M=Al, Ga; R=alkyl) both forms are almost equal in energy.

AbstractThe hydroxo compounds [Re(OH)(CO)3(NN)] (NN=bipy, 2 a; Me2bipy, 2 b) were prepared in a biphasic H2O/CH2Cl2 medium by reaction of [Re(OTf)(CO)3(NN)] with KOH. In contrast, when anhydrous CH2Cl2 was used, the binuclear hydroxo‐bridged compound [{Re(CO)3(bipy)}2(μ‐OH)]OTf (3‐OTf) was obtained. Compound [Re(OH)(CO)3(Me2bipy)] (2 b) reacted with phenyl acetate or vinyl acetate to afford [Re(OAc)(CO)3(Me2bipy)] (4) and phenol or acetaldehyde, respectively. The reactions of [Mo(OH)(η3‐C3H4Me‐2)(CO)2(phen)] (1), 2 a, and 2 b toward several unsaturated organic electrophiles were studied. The reaction of 1 with (p‐tolyl)isocyanate afforded an adduct of N,N′‐di(p‐tolyl)urea and the carbonato‐bridged compound [{Mo(η3‐C3H4Me‐2)(CO)2(phen)}2(μ‐η1(O),η1(O)‐CO3)] (5). In contrast, the reaction of 2 a with phenylisocyanate afforded [Re(OC(O)NHPh)(CO)3(bipy)] (6); this results from formal PhNCO insertion into the OH bond. On the other hand, compounds [Mo[SC(O)NH(p‐tolyl)](η3‐C3H4Me‐2)(CO)2(phen)] (7), [Re[SC(O)NH(p‐tolyl)](CO)3(Me2bipy)] (8 a), and [Re[SC(O)NHEt](CO)3(Me2bipy)] (8 b) were obtained by reaction of 1 or 2 b with the corresponding alkyl or aryl isothiocyanates. In those cases, RNCS was inserted into the MO bond. The reactions of 1, 2 a, and 2 b with dimethylacetylenedicarboxylate (DMAD) gave the complexes [Mo[C(OH)C(CO2Me)C(CO2Me)O](η3‐C3H4Me‐2)(CO)(phen)] (9) and [Re[C(OH)C(CO2Me)C(CO2Me)O](CO)2(NN)] (NN=bipy, 10 a; Me2bipy, 10 b). The molecules of these compounds contain five‐membered metallacycles that are the result of coupling between the hydroxo ligand, DMAD, and one of the CO ligands. The new compounds were characterized by a combination of IR and NMR spectroscopy, and for [{Re(CO)3(bipy)}2(μ‐OH)]BF4 (3‐BF4), 4, 5, 6, 7, 8 b, 9, and 10 b, also by means of single‐crystal X‐ray diffraction.
Reactions of Copper(II) Salts with 3{5}‐tert‐Butylpyrazole: Double‐Cubane Complexes with Bound Exogenous Anions, and a Novel Pyrazole Coordination Mode

AbstractReaction of CuX2 (X−Cl−, Br−, NO3−), NaOH, and 3{5}‐tert‐butylpyrazole (HpztBu) in a 1:1:2 molar ratio in MeOH at 293 K for three days affords [{Cu3(HpztBu)6(μ3‐X)(μ3‐OH)3}2Cu]X6 (X−Cl−, 1; X−Br−, 2; X−NO3−, 3) in moderate yields. These compounds contain a centrosymmetric, vertex‐sharing double‐cubane [{Cu3(HpztBu)6(μ3‐X)(μ3‐OH)3}2Cu]6+ core, surrounded by a belt of six hydrogen‐bonded X− ions. For 1 and 2, the ring of guest anions has near C3 symmetry, that is slightly distorted owing to the axis of Jahn–Teller elongation at the central Cu ion. For 3 only, the NO3− guest ions are crystallographically disordered, reflecting their poor complimentarity with complex host. A similar reaction employing CuF2 yields [{Cu3(HpztBu)4(μ‐pztBu)2(μ‐F)2(μ3‐F)}2]F2 (4), whose structure contains a cyclic hexacopper core with approximate C2v symmetry. Finally, an analogous reaction using Cu(NCS)2 gives a mixture of trans‐[Cu(NCS)2(HpztBu)2] (5) and [Cu2(NCS)2(μ‐pztBu)2(μ‐HpztBu)(HpztBu)2] (6). The latter compound contains a HpztBu ligand bridging the two Cu ions in an unusual κ1,μ‐coordination mode. The variable temperature magnetic properties of 1–3 show antiferromagnetic behavior, leading to a S=${{ 1/2 }}$ ground state in which the seven copper(II) ions are associated into three mutually independent distinct spin systems. In confirmation of this interpretation, Q‐band EPR spectra of solid 1 and 2 at 5 K also demonstrate a S=${{ 1/2 }}$ spin system and exhibit hyperfine coupling to three 63,65Cu nuclei. Unusually, the coupling is manifest as an eight‐line splitting of the parallel feature, rather than the usual 10 lines. This has been rationalized by a spin‐projection calculation, and results from the relative magnitudes of coupling to the three Cu nuclei. UV/Vis and mass spectrometric data show that 1–4 decompose to lower nuclearity species in solution.
First Systematic Investigation of CH⋅⋅⋅Cl Hydrogen Bonding Using Inorganic Supramolecular Synthons: Lamellar, Stitched Stair‐Case, Linked‐Ladder, and Helical Structures
Authors: Balamurugan V. , Hundal Maninder Singh , Mukherjee Rabindranath 
Published: March 2004

AbstractUsing a group of six neutral MIICl2‐containing coordination compounds as building blocks, the first systematic investigation of CH⋅⋅⋅Cl hydrogen‐bonding interactions was performed. Single‐crystal X‐ray structural analyses of four new compounds (pseudo‐tetrahedral CoII and ZnII; distorted trigonal bipyramidal ZnII) authenticate the metal coordination geometry. To provide a unified view of the presence of noncovalent interactions in this class of compounds, we have re‐examined the packing diagram of two previously reported compounds (a distorted square‐pyramidal CuII complex and a trans‐octahedral CoII complex). The organic ligands of our choice comprise bidentate/tridentate pyrazolylmethylpyridines and an unsymmetrical tridentate pyridylalkylamine. This systematic investigation has allowed us to demonstrate the existence of versatile CH⋅⋅⋅Cl2M interactions and to report the successful application of such units as inorganic supramolecular synthons. Additional noncovalent interactions such as CH⋅⋅⋅O and OH⋅⋅⋅Cl hydrogen bonding and π–π stacking interactions have also been identified. Formation of novel supramolecular architectures has been revealed: 2D lamellar (p‐cyclophane) and 3D lamellar, 3D “stitched staircase” (due to additional hydrogen‐bonding interactions by water tetramers, with an average OO bond length in the tetramer unit of 2.926 Å, acting as “molecular clips” between staircases), 3D linked ladder, and single‐stranded 1D helix.

Published: March 2004

AbstractBiomolecular motors, in particular motor proteins, are ideally suited to introduce chemically powered movement of selected components into devices engineered at the micro‐ and nanoscale level. The design of such hybrid “bio/nano”‐devices requires suitable synthetic environments, and the identification of unique applications. We discuss current approaches to utilize active transport and actuation on a molecular scale, and we give an outlook to the future.

Authors: Deacon Glen B. , Forsyth Craig M. 
Published: March 2004

AbstractTetraphenylborate salts of solvated pentafluorophenyllanthanoid(II) cations [Ln(C6F5)(thf)n]+ (Ln=Eu, n=6 (1); Ln=Yb, n=5 (2)) were readily synthesized in high yield by reactions of ytterbium or europium with HgPh(C6F5) and Me3NHBPh4 in THF. The structures of 1⋅THF and 2 confirmed the existence of well‐separated ions and both 1 and 2 show notable thermal stability at room temperature. The cation in 2 was also observed in the remarkable mixed‐valent complex [YbII(C6F5)(thf)5][YbIII(C6F5)2{N(SiMe3)2}2] (3), fortuitously isolated in low yield from a reaction of ytterbium metal, HgPh(C6F5), and HN(SiMe3)2 in THF, and which additionally has an unusual bis(pentafluorophenyl)bis{bis(trimethylsilyl)amido)}ytterbate(III) anion. 171Yb–19F coupling has been observed in the low‐temperature 171Yb NMR spectra of 2 and [Yb(C6F5)2(thf)4].
Growing ZnO Crystals on Magnetite Nanoparticles
Authors: Turgeman Rachel , Tirosh Shay , Gedanken Aharon 
Published: March 2004

AbstractWe report herein on the oriented growth of ZnO crystals on magnetite nanoparticles. The ZnO crystals were grown by hydrolyzing a supersaturated aqueous solution of zinc nitrate. The seeds for the growth were magnetite nanoparticles with a diameter of 5.7 nm and a narrow size distribution. Hollowed ZnO hexagons of 0.15 μm width and 0.5 μm length filled with Fe3O4 particles were obtained. HR‐TEM (high‐resolution transmission electron microscopy) and selected‐area EDS (energy‐dispersive spectroscopy) show that the nanoparticles are homogenously spread in the ZnO tubes. Zeta potential measurements were employed to understand the relationship between the nanoparticles and the oriented growth of the ZnO crystals. The results show that the surfactants induced the directional growth of the ZnO crystals.
