Carmona, A.; Corma, A.; Iglesias, M.; Sanchez, F. published the article 《Synthesis and characterization of chiral Cu(I) complexes of substituted pyrrolidine ligands. Efficient catalysts for cyclopropanation reactions》. Keywords: chiral copper complex substituted pyrrolidine catalyst; cyclopropanation catalyst chiral copper substituted pyrrolidine; styrene cyclopropanation chiral copper substituted pyrrolidine.They researched the compound: Chloro(1,5-cyclooctadiene)copper(I) dimer( cas:32717-95-6 ).Quality Control of Chloro(1,5-cyclooctadiene)copper(I) dimer. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:32717-95-6) here.
A series of new copper(I) complexes of chiral bidentate N,N’-ligands ((S)-2-t-butylaminocarbonylpyrrolidine, (S)-1,2-(bis-t-butyl-aminocarbonyl)pyrrolidine, (S)-1-t-butylaminocarbonyl-2-(1-naphthylaminocarbonyl)pyrrolidine, (S)-1-t-butylaminocarbonyl-2-(1-naphthylaminomethyl)pyrrolidine, (2S,4S)-1,2-(bis-t-butylaminocarbonyl)-4-aminopyrrolidine) of general formula [Cu(CH3CN)(L-L)]X (X = PF6, ClO4) have been synthesized and fully characterized by elemental anal., IR, electronic and NMR spectroscopy. These complexes catalyze the cyclopropanation of styrene, used as a model for monosubstituted olefins, with Et diazoacetate to yield a mixture of cis/trans Et 2-phenylcyclopropan-1-carboxylates with up to 30% ee.
