Arenethiolatocopper(I) complexes as homogeneous catalysts for Michael addition reactions

Asymmetric Conjugate Reduction of α,β‐Unsaturated Ketones and Esters with Chiral Rhodium(2,6‐bisoxazolinylphenyl) Catalysts

“…DAICEL CHIRALCEL AD-H column, 0.5 mL min À1 , iPrOH/hexane 1:99, R t = 9.6 min (minor), [16] [a] 22 D = À56.48 (c = 1.0 in benzene) for R. NMR and IR spectroscopic data were consistent with that previously reported. [16] (R)-2-Methyl-5-phenyl-3-hexanone (11): [17] Spectroscopic data of NMR and IR were consistent with previously reported data. [18] (S)-5-Methyl-4-phenyl-2-hexanone (15): [20,21] Yield: 97 % (185 mg, 0.97 mmol), colorless oil.…”

Synthesis of ligands based on naphthalene peri-substituted by Group 15 and 16 elements and their coordination chemistry

“…The intramolecularly coordinating amine group in 131 is believed to contribute to the well-defined structure of the cluster. The complex has been used as a catalyst in a number of transformations [119][120][121].…”

A recyclable nanosize aminoarenethiolato copper(I) catalyst for C–C coupling reactions

“…thermally stable and have considerable stability towards oxidation by air. Furthermore, mechanistic studies established that the covalent thiolato-copper bond is maintained throughout the catalytic cycle in processes involving the use of RLi [13], RMgX [6] and R 2 Zn reagents [14]. A recent example, shown in Fig.…”

“…In particular the catalytic activity of aminoarenethiolato copper(I) 1a has been extensively studied, which appeared to have wide applicability as stable catalysts in, e.g. 1,4-additions [6][7][8][9], 1,6-additions [10] and allylic substitutions [11,12]. Although it is not the most active copper catalyst reported to date, recent studies showed that these aminoarenethiolato copper(I) catalysts are very robust, i.e.…”
