A series of molybdenum and tungsten nitrido, [M(N)(X)(diphos)2], and imido complexes, [M(NH)(X)(diphos)2)]Y, (M = Mo, W) with diphosphine coligands (diphos = dppe/depe), various trans ligands (X = N3-, Cl-, NCCH3) and different counterions (Y-= Cl-, BPh4-) is investigated. These compounds are studied by infrared and Raman spectroscopies; they are also studied with isotope-substitution and optic...

Antimicrobial peptides (AMPs) kill microorganisms by causing structural damage to bacterial membranes. Different often require a different type and concentration of an AMP achieve full microbial killing. We hypothesise that the difference is caused membrane structure composition. Given complexities membranes, we have used monolayers binary DPPG/TMCL mixture mimic cytoplasmic Gram-positive bacte...

Reaction of 2-X-N-methylbenzimidazole (X = chloro, iodo) with Ni(0) complexes in the presence of dppe or PEt(3) and an external proton source yielded via an oxidative addition reaction nickel(II) complexes bearing NH,NMe-functionalized NHC ligands.

The NiBr2(dppe)-Zn system effectively catalyzes the [2 + 2 + 2] cocyclotrimerization of arynes with diynes, leading to substituted naphthalene derivatives in moderate to good yields. This cocyclotrimerization reaction shows excellent tolerance of functional groups and leads to products of 5- to 7-membered fused-ring sizes.

A family of hexa-coordinated ruthenium(II) complexes of bis(N-pyridylimidazolylidenyl)methane (L) were prepared and structurally characterized. Carbene transfer reactions of [Ru(p-cymene)Cl(2)](2), [Ru(CO)(2)Cl(2)](n) and RuHCl(CO)(PPh(3))(3) with silver-NHC complexes in situ generated from [H(2)L](PF(6))(2) and Ag(2)O afforded [RuL(CH(3)CN)(2)](PF(6))(2) (1), [Ru(2)L(p-cymene)(2)Cl(2)](PF(6))(...

A bi-catalytic system, in which Ru-MACHO-BH and Ru(H)2(dppe)2 interact in a synergistic manner, was developed for the base-free dehydrogenation of methanol. A total TON > 4200 was obtained with only trace amounts of CO contamination (<8 ppm) in the produced gas.

A copper/N-heterocyclic carbene (NHC) catalyzed oxidative vicinal diphosphination of styrenes with diphenyl(trimethylsilyl)phosphine proceeds in the presence of LiOtBu and a pyridine N-oxide/MnO2 combined oxidant to deliver the corresponding 1,2-bis(diphenylphosphino)ethanes (DPPEs) in good yields. The present copper catalysis can provide access to the DPPE-type ligands directly from the relati...
