Going to the source: The trifluoromethylation of aryl/heteroaryl iodides has been demonstrated using a flow system, thus enabling a rapid rate of reaction. A broad spectrum of trifluoromethylated compounds was prepared in good to excellent yields using CF3 CO2 K as the trifluoromethyl source. The process has the advantage of short reaction times and uses convenient [CF3 ] sources.

The use of model organisms, such as Drosophila melanogaster, provides a powerful method for studying mechanisms of aging. Here we report on a large set of recombinant inbred (RI) D. melanogaster lines that exhibit approximately a fivefold range of average adult longevities. Understanding the factors responsible for the differences in longevity, particularly the characteristics of the longest-li...

Static and dynamic magnetic properties of the tetracoordinate CoII complex [Co(CH3-im)2Cl2], (1, CH3-im = N-methyl-imidazole), studied using thorough analyses of magnetometry, and High-Frequency and -Field EPR (HFEPR) measurements, are reported. The study was supported by ab initio complete active space self-consistent field (CASSCF) calculations. It has been revealed that 1 possesses a large m...

Ethylene glycol (EG) oxidation has been studied on Pt(111) and its vicinal surfaces in acidic media by cyclic voltammetry and infrared spectroscopy. Even at Pt(111) the C-C bond is readily broken and CO is formed at low potentials. Both types of steps catalyze the EG oxidation to CO2, being the {110} steps the most catalytic for the splitting of the C-C bond. Spectroscopic results show that gly...

Dried and ground leaves of Crithmum maritimum were used as a matrix for supercritical extraction of volatile oil with CO2. Operative conditions were: extractor, 90 bar and 50 °C for 240 min; first separator, 90 bar and –10°C; second separator, 15 bar and 15 °C. GC/MS analysis of the leaves volatile oil revealed that it mainly consisted of: para-cymene, βphellandrene, γ-terpinene, thymol methyl ...
