Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Chloro(1,5-cyclooctadiene)copper(I) dimer, is researched, Molecular C16H16Cl2Cu2, CAS is 32717-95-6, about Synthesis and characterization of chiral Cu(I) complexes of substituted pyrrolidine ligands. Efficient catalysts for cyclopropanation reactions.Recommanded Product: Chloro(1,5-cyclooctadiene)copper(I) dimer.
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.
