The homogeneous electrochemical reduction of CO2 by the molecular catalyst [Ni(cyclam)]2+ is studied by electrochemistry and infrared spectroelectrochemistry. The electrochemical kinetics are probed by varying CO2 substrate and proton concentrations. Products of CO2 reduction are observed in infrared spectra obtained from spectroelectrochemical experiments. The two major species observed are a Ni(I) carbonyl, [Ni(cyclam)(CO)]+, and a Ni(II) coordinated bicarbonate, [Ni(cyclam)(CO2OH)]+. The rate-limiting step during electrocatalysis is determined to be CO loss from the deactivated species, [Ni(cyclam)(CO)]+, to produce the active catalyst, [Ni(cyclam)]+. Another macrocyclic complex, [Ni(TMC)]+, is deployed as a CO scavenger in order to inhibit the deactivation of [Ni(cyclam)]+ by CO. Addition of the CO scavenger is shown to dramatically increase the catalytic current observed for CO2 reduction. Evidence for the [Ni(TMC)]+ acting as a CO scavenger includes the observation of [Ni(TMC)(CO)]+ by IR. Density functional theory (DFT) calculations probing the optimized geometry of the [Ni(cyclam)(CO)]+ species are also presented.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 41203-22-9 is helpful to your research. name: 1,4,8,11-Tetramethyl-1,4,8,11-tetraazacyclotetradecane

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1802-30-8, molcular formula is C12H8N2O4, introducing its new discovery.

Electric Literature of 23364-44-5, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 23364-44-5, Name is (1S,2R)-2-Amino-1,2-diphenylethanol, molecular formula is C14H15NO.

A series of beta-amino alcohol analogs of sugiol were synthesized in a straightforward manner. The in vitro antiproliferative activities were examined in the human solid tumor cell lines A2780, SW1573 and WiDr. The most potent analogs induced considerably growth inhibition in the range 1.5-6.7 muM. The results showed that beta-amino alcohol analogs are more potent than the parent compound. In addition, the derivatives with secondary amine fragments showed more active than those bearing tertiary amines.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 23364-44-5, you can also check out more blogs about23364-44-5

Group IV metallocene triphenylsiloxy chlorides, Cp2MCl(OSiPh 3) (1, M=Ti; 2, M=Zr; 3, M=Hf), and cyclic organohydroborates, Cp2M(OSiPh3){(mu-H)2BC8 H14} (4, M=Zr; 5, M=Hf), were synthesized and characterized. The new hafnocene chloride derivative 3 was obtained by treating Cp2HfCl2 with triphenylsilanol and piperidine. The 18-electron cyclic organohydroborates 4 and 5 were afforded by reacting 2 and 3 with K[H2BC8H14], the potassium salt of the 9-BBN dimer. Reaction of 1 with K[H2BC8 H14] causes reduction of the Ti(IV) center and produces the well-known Ti(III), 17-electron, paramagnetic dimer [Cp2Ti (mu-Cl)2TiCp2] (6). Single-crystal X-ray diffraction structures of 3, 4, 5, and 6 were determined.

In Latin America Chagas disease is an endemic illness caused by the parasite Trypanosoma cruzi (T. cruzi), killing more people than any other parasitic disease. Current chemotherapies are old and inadequate, thus the development of efficient ones is urgently needed. Vanadium-based complexes have been shown to be a promising approach both against parasitic diseases and cancer and this study aims to achieve significant advances in the pursue of effective compounds. Heteroleptic vanadium complexes of Schiff bases and polypyridine compounds were prepared and their stability in solution evaluated by EPR (Electronic Paramagnetic Resonance) and NMR spectroscopy. Their in vitro activities were evaluated against T. cruzi and a set of cell lines representative of human cancer conditions, namely ovarian, breast and prostate cancer. In T. cruzi, most of the complexes depicted IC50 values in the low muM range, induced changes of mitochondrial membrane potential and apoptosis. In cancer cells, complexes showed good to moderate activity and in metastatic cells (prostate PC3), some complexes inhibited the migratory ability, this suggesting that they display antimetastatic potential. Interestingly, complex 5 seemed to have a dual effect being the most cytotoxic complex on all cancer cells and also the most active anti-T-cruzi compound of the series. Globally the complexes showed promising anticancer and anti T. cruzi activities and also displayed some characteristics indicating they are worth to be further explored as antimetastatic drugs.
