The Ir(III) complex [Ir2H2I3((rac)-Binap)(2)]I-+(-) efficiently promotes the selective dimerization of 1,6-, 1,7-enynes and functionalized alkynes. This catalytic process results in the formation of head-to-head isomers ...
Organotin impurities in product mixtures can be reduced from stoichiometric levels to similar to 15 parts per million by column chromatography using 10% w/w anhydrous potassium carbonate-silica as a stationary phase.
In this work, we combine reversible addition fragmentation transfer polymerization (RAFT) with cobalt catalytic chain transfer (CCT) to obtain x-unsaturated polymers with relatively low polydispersity values.
An efficient synthetic method for producing indolizines through a tandem Pd-catalyzed selective allenyl cross-coupling reaction using organoindium reagents and cycloisomerization was developed in a one-pot process.
The interactions of the metal ions Mg2+, Zn2+, Ni2+, and Co2+ with thin films of peptide nucleic acids (PNAs) were studied by electrochemical impedance spectroscopy (EIS), and the results show that Zn2+, Ni2+ and Co2+ in...
Thermally stable mesoporous Ga-Nb mixed oxides, active in both acid-catalysed and redox reactions have been synthesized via self-assembly hydrothermal assisted approach. Methyl oleate, a major component of biodiesels, un...
An operationally simple iron-catalyzed hydrodehalogenation of aryl halides has been developed with 1 mol% Fe(acac) 3 and commercial t-BuMgCl as reductant. The mild reaction conditions (THF, 0 degrees C, 1.5 h) effect rap...
Selective oxidation of alcohol in water using molecular oxygen as the terminal oxidant is mediated by rhodium porphyrin complexes. Addition of methanol to an aqueous solution of (TSPP) Rh(III) resulted in observation of ...
A highly efficient silver triflate and N-heterocyclic carbene co-catalyzed three-component reaction of N'-(2-alkynylbenzylidene)hydrazide, methanol with alpha,beta-unsaturated aldehyde is described, which gives rise to t...
Fluorescence resonance-energy-transfer occurred in a solution of Rhodamine 6G in an ionic liquid by excitation at wide wavelength areas owing to specific fluorescent behavior of the ionic liquid to show emissions at each...
A [Co-24] metallamacrocycle with a [36-MCCo-12] periphery and an inner [24-MCCo-6] rim is constructed by linking six Co-4-thiacalixarene shuttlecock-like SBUs with twelve 1,2,4-triazole molecules.
We demonstrate facile synthesis of mesoporous Pt replicas using double gyroid mesoporous silica (KIT-6) with different pore diameters via vapor infiltration of a reducing agent. Through controlling the complementary pore...
Liquid-assisted grinding allows the rapid, waste-free and one-pot synthesis of a variety of magnesium drug derivatives directly from the excipient MgO; such reactivity is relevant for the behaviour of ibuprofen formulati...
Galvanic reactions of Hg2+, Rh3+, and AuCl4- ions with Ag nanoparticles positioned near the surface and throughout the matrix of host poly(perfluorosulfonic) acid membrane have been studied.
Fluorescent silica nanoparticles deposited with highly mono-disperse gold nanoparticles (1-2 nm) were synthesized via the W/O method and intensive ultrasound irradiation. A large surface area of gold-doped fluorescent si...
Pt-free cathode catalysts for polymer electrolyte membrane fuel cells have been prepared by multi-step pyrolysis of FePc and PhRs, in the best of which show extensively high initial cell performance and good durability c...
