Heteroditopic P,N ligands in gold(I) complexes: Synthesis, structure and cytotoxicity

New heteroditopic, bi- and multidentate imino- and aminophosphine ligands were synthesised and complexed to [AuCl(THT)] (THT = tetrahydrothiophene). X-ray crystallography confirmed Schiff base formation in three products, the successful reduction of the imino-group to the sp3-hybridised amine in several instances, and confirmed the formation of mono-gold(I) imino- and aminophosphine complexes for four Au-complexes. Cytotoxicity studies in cancerous and non-cancerous cell lines showed a marked increase in cytotoxicity upon ligand complexation to gold(I). These findings were supported by results from the 60-cell line fingerprint screen of the Developmental Therapeutics Programme of the National Institutes of Health for two promising compounds. The cytotoxicity of some of these ligands and gold(I)complexes is due to the induction of apoptosis. The ligands and gold(I)complexes demonstrated selective toxicity towards specific cell lines, with Jurkat T cells being more sensitive to the cytotoxic effects of these compounds, while the non-cancerous human cell line KMST6 proved more resistant when compared to the cancerous cell lines. Results from the NIH DTP 60 cell-line fingerprint screen support the observed enhancement of cytotoxicity upon gold(I) complexation. One gold(I)complex induced high levels of apoptosis at concentrations of 50 muM in all the cell lines screened in this study, while some of the other compounds selectively induced apoptosis in the cell lines. These results point towards the potential for selective toxicity to cancerous cells through the induction of apoptosis.

Electron transfer from hexameric copper hydrides

The octahedral core of 84-electron LCuH hexamers does not dissociate appreciably in solution, although their hydride ligands undergo rapid intramolecular rearrangement. The single-electron transfer proposed as an initial step in the reaction of these hexamers with certain substrates has been observed by stopped-flow techniques when [(Ph3P)CuH]6 is treated with a pyridinium cation. The same radical cation has been prepared by the oxidation of [(Ph3P)CuH]6 with Cp* 2Fe+ and its reversible formation observed by cyclic voltammetry; its UV-vis spectrum has been confirmed by spectroelectrochemistry. The 48-electron trimer [(dppbz)CuH]3 has been prepared by use of the chelating ligand 1,2-bis(diphenylphosphino)benzene (dppbz).

Silver(I) poly(1,2,3-benzotriazolyl)borate complexes containing mono- and bidentate phosphine coligands

New silver(I) derivatives [Ag{HnB(btz)4 – n}(PR 3)x] (n = 1 or 2, x ranging from 1 to 3), containing monodentate tertiary phosphines and anionic poly(benzotriazol-1-yl)borates, have been prepared from the reaction of AgNO3 with PR3 (R = Ph, o-tolyl, m-tolyl, p-tolyl, Bns) and K[H2B(btz)2], or K[HB(btz)3] (Hbtz = 1,2,3-benzotriazole). When the reaction between K[H2B(btz)2] and AgNO3 was carried out in the presence of dppe (1,2-bis(diphenylphosphino)ethane), or dppf (1,1?-bis(diphenylphosphino)ferrocene), compounds [Ag{H 2B(btz)2}]2(L) (L = dppe or dppf) formed, the diphosphine acting as a bidentate bridging P2-donor. Solid state and solution properties of all complexes have been investigated through analytical and spectroscopic measurements (IR, 1H, 31P NMR), the 1H and 31P NMR spectra being interpreted in terms of equilibria that involve mono- and di-nuclear complexes. Adducts [Ag{HB(btz) 3}(PPh3)3] ? (1/2H2O) and [Ag{H2B(btz)2}]2 (dppf) have been characterised by single crystal X-ray studies. In the former, the HB(btz)3 is unidentate in an NAgP3 coordination environment; the latter is a dimer, the dppf bridging the two silver atoms, while the H2B(btz) 2 ligand, which chelates one silver, bridges to the second also, the array having 2-symmetry.

Carbon dioxide conversion to synthetic fuels using biocatalytic electrodes

Carbon dioxide has evolved from being considered as a greenhouse gas to a valuable carbon feedstock for the generation of artificial fuels and valuable chemicals. In this work, we review the biocatalytic approaches towards CO2 conversion into chemicals and fuels. We display the opportunities and challenges of using biocatalysts. Our work especially focuses on bio-electrocatalytic systems. These electrochemical applications of biocatalysts gain increasing interest, as electrochemical redox processes can avoid expensive mediators and co-factors. This is also a pathway for renewable energy storage because wind or solar energy can possibly be applied as electrical sources for the electrochemical CO2 conversion systems. Biocatalytic CO2 conversion together with renewable energy storage represents a viable and sustainable route for the generation of chemicals and fuels.

Synthesis of N-Acyl-, N-Sulfonyl-, and N-Phosphinylphospha-lambda5-azenes by a Redox-Condensation Reaction Using Amides, Triphenylphosphine, and Diethyl Azodicarboxylate

The reaction of phosphines and amides with diethyl azodicarboxylate (DAD) produced phospha-lambda5-azenes.Thus aromatic amides and those aliphathic amides with electron-withdrawing substituents gave N-acyl-P,P,P-triphenylphospha-lambda5-azenes (5) when triphenylphosphine (TPP) was employed.Both aryl- and alkylsulfonamides reacted with TPP and DAD to produce the N-sulfonylphospha-lambda5-azenes (9).Diphenylphosphinamide (10) and ethyl carbamate (12) also produced the respective phosphazenes (11 and 13) with TPP and DAD.Secondary carboxamides and sulfonamides did not react with TPP and DAD.The reaction of triethyl phosphite with sulfonamides in the presence of DAD produced the phosphorimidates (20) in an analogous reaction, along with the corresponding N,N-diethylsulfonamides and the deethylated adduct of triethyl phosphite and DAD (23).Triethyl phosphite-DAD failed, however, to give a phosphorimidate with carboxamides but gave, instead, the rearranged adduct of DAD and triethyl phosphite (19).Tris(dimethylamino)phosphine reacted with sulfonamides and DAD but the products were the corresponding ethyl N-sulfonylcarbamates (26) rather than the phosphazenes.Tris(dimethylamino)phosphine reacted with azodicarbonamide (a molecule which contains both the azo and carboxamide groups) with the production of N,N-dimethylurea, again without formation of the phosphazene.Finally, the reaction of triphenylarsine with benzenesulfonamide and DAD produced N-(phenylsulfonyl)triphenylarsa-lambda5-azene (30) but triphenylstibene with DAD and benzenesulfonamide only gave triphenylstibene oxide.Mechanistic possibilities for these reactions are also discussed.
