Extraction - Spectrophotometric Determination of Palladium with Tetrabutyl Ammonium Iodide
A sensitive and selective extraction - spectrophotometric method for the determination of trace amounts of palladium is reported. The method is based on quantitative extraction of brownish tetrabutylammoium tetraiodopalladium (II) ion pair into a small valume of chloroform at pH 1.3-12.0, followed by spectrophotometric measurements. The Beer's law is obeyed over the range 0.02-1.09 <em...

متن کاملPalladium-catalyzed atom transfer radical cyclization of unactivated alkyl iodide.
A palladium-catalyzed atom transfer cyclization of unactivated alkyl iodide has been developed. A radical chain mechanism has been proposed for this transformation, which might not involve an alkylpalladium intermediate.
متن کاملPalladium-Catalyzed Monofluoromethylation of Arylboronic Esters with Fluoromethyl Iodide.
The first palladium-catalyzed direct monofluoromethylation of arylboronic esters to produce monofluoromethyl arenes is reported. The reaction is typically carried out at room temperature within 4 h and has a good functional group tolerance. The monofluoromethylating agent, CH2FI, was readily prepared via a halogen-exchange process.
متن کاملThe palladium-catalyzed cross-coupling reactions of trifluoroethyl iodide with aryl and heteroaryl boronic acid esters.
The cross-coupling reactions of 1,1,1-trifluoro-2-iodoethane with aryl and heteroaryl boronic acid esters have been successfully achieved. The new protocol allows for a convenient introduction of trifluoroethyl groups into a variety of aryl and heteroaryl moieties under mild conditions.
