So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Carmona, A.; Corma, A.; Iglesias, M.; Sanchez, F. researched the compound: Chloro(1,5-cyclooctadiene)copper(I) dimer( cas:32717-95-6 ).Synthetic Route of C16H16Cl2Cu2.They published the article 《Synthesis and characterization of chiral Cu(I) complexes of substituted pyrrolidine ligands. Efficient catalysts for cyclopropanation reactions》 about this compound( cas:32717-95-6 ) in Inorganica Chimica Acta. Keywords: chiral copper complex substituted pyrrolidine catalyst; cyclopropanation catalyst chiral copper substituted pyrrolidine; styrene cyclopropanation chiral copper substituted pyrrolidine. We’ll tell you more about this compound (cas:32717-95-6).
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.
As far as I know, this compound(32717-95-6)Synthetic Route of C16H16Cl2Cu2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
