JOURNAL FREE ACCESSLithium dialkylcopper, cuprate, is prepared in situ by treating a suspension of cuprous iodide in ether or THF with 2 equivalent of alkyllithium. Anhydrous cupric chloride is prepared by heating commercially available CuCl2·2H2O at 120°C for several hours. Cuprous oxide is prepared by heating commercially available Cu2O in vacuo at 6070°C for several hours. Copper (I) carbonyl cation is generated by treating cuprous oxide in sulfuric acid with 1 atm. of carbon monoxide. Active copper powder is prepared by reducing cupric sulfate in water with zinc powder under nitrogen gas. Copper (I) tert-butoxide is prepared by reacting anhydrous cuprous chloride with lithium tert-butoxide in THF. Copper (I) tert-butoxide is thermally stable under nitrogen and purified by sublimation at 170°C/1 mmHg. Copper (I) triflate · (benzene) 1/2 complex is prepared by heating cuprous oxide with trifluoromethanesulfonic acid anhydride in benzene at reflux.

Applications of (Arene) tricarbonylchromium Complexes in Organic SynthesisMasaaki YOSHIFUJI1979 Volume 37 Issue 12 Pages 1034-1036
Published: December 01, 1979
Released on J-STAGE: November 13, 2009
JOURNAL FREE ACCESS(Arene) tricarbonylchromium complexes can be prepared simply by heating arenes with hexacarbonylchromium in high yield. These complexes undergo selective reactions on or adjacent to metal-complexed aromatic rings; removal of electron density from the arenes through coordination allows nucleophilic reactants to add to a carbon of the arene ring under mild reaction conditions and the bulky Cr (CO) 3 moiety can exert a large steric blocking effect causing stereo-selective reactions. Some typical experimental procedures are described.View full abstractDownload PDF (424K) -

Rhodium and Iridium CompoundsTakamichi YAMAGISHI1979 Volume 37 Issue 12 Pages 1072-1080
Published: December 01, 1979
Released on J-STAGE: November 13, 2009
JOURNAL FREE ACCESSSince the prominent application of the Wilkinson complex to the hydrogenation of olefins, many organic reactions catalyzed by rhodium complexes and iridium analogs have been reported. In this review, the preparative methods, properties of rhodium compounds and their applications to organic synthesis as well as those of iridium compounds are described. Rhodium and iridium compounds are generally prepared starting from their water-soluble halogeno compounds such as RhCl3·3H2O or IrCl3H2O. The oxidation state of the compounds obtained is strongly dependent on the nature of the ligands. Low-valent (from -3 to zero) complexes are stabilized by carbon monoxide which behaves as a strong π-acceptor. Uni-valent complexes are coordinated by olefins, dienes, carbon monoxide, phosphines, arsines or amines. Most of low-valent complexes are air-sensitive and should be handled under inert atmosphere. They easily undergo the oxidative addition reaction and catalyze organic reactions, such as hydrogenation, hydrosilylation, hydroformylation, oligomerization, isomerization, carbonylation, decarbonylation, etc.View full abstractDownload PDF (1180K) -
