Trifluoromethyl-substituted pyridines through displacement of iodine by in situ generated (trifluoromethyl)copper

Fabrice Cottet

A literature method reported for the prepn. of trifluoromethyl substituted benzenes from iodobenzene and congeners was successfully extended to the pyridine series. 2-Iodopyridines can be converted into 2-(trifluoromethyl)pyridines almost quant. by displac ...

On detection of the Fermi edge in in situ grown thin films of high-T-c oxides

Giorgio Margaritondo, Davor Pavuna, Mike Abrecht

We discuss our systematic series of experiments on the photoelectric detection of the Fermi edge using a cylindrical mirror analyser on films of high-T-c oxides. grown in situ by pulsed laser ablation. The Fermi edge (comparable to the edge of the referenc ...

In-situ OH kinetics study providing an indicator for ozone formation limitation

Hubert van den Bergh, Bertrand Calpini, Alain Clappier

Hydroxyl radicals dominate daytime tropospheric chem., responsible for reactive removal of most trace gases (e.g., volatile org. compds.[VOC]), and is an active participant in the NO and NO2 cycle. Pump-and-probe LIDAR was used to examine the OH- chem. in ...
