متن کاملCopper Chemistry
Humans first used copper about 10,000 years ago. A copper pendant discovered in Northern Iraq is thought to date back to around 8700 BC. Prehistoric man probably used copper for weapon making. Ancient Egyptians too seemed to have appreciated the corrosion resistance of the metal. They used copper bands and nails in ship building and copper pipes were used to convey water. Some of these artifact...
متن کاملCross-Coupling Chemistry at Mononuclear and Dinuclear Nickel Complexes
SYNLETT 2011, No. 1, pp 0001–0005xx.xx.2010 Advanced online publication: 16.12.2010 DOI: 10.1055/s-0030-1259093; Art ID: P00110ST © Georg Thieme Verlag Stuttgart · New York Abstract: Nickel catalysts have been developed for a wide range of C–C bond formation reactions. Reaction mechanisms proposed for these transformations generally involve catalytic intermediates based on mononickel species. T...
متن کاملCopper(i)-catalyzed sulfonylative Suzuki-Miyaura cross-coupling.
Using a simple copper(i) catalyst has allowed a high yielding sulfonylative-Suzuki-Miyaura cross-coupling reaction to be developed. The process provides a single step route to diaryl sulfones from the direct combination of aryl boronic acids, sulfur dioxide and aryl iodides, and represents the first sulfonylative variant of a classic cross-coupling reaction. Sulfur dioxide is delivered from the...
متن کاملRoom temperature aryl trifluoromethylation via copper-mediated oxidative cross-coupling.
A method for the room temperature copper-mediated trifluoromethylation of aryl and heteroaryl boronic acids has been developed. This protocol is amenable to normal benchtop setup and reactions typically require only 1-4 h. Proceeding under mild conditions, the method tolerates a range of functional groups, allowing access to a variety of trifluoromethylarenes.
