A scalable enantioselective nickel-catalyzed electrochem. reductive homocoupling of aryl bromides has been developed, affording enantioenriched axially chiral biaryls in good yield under mild conditions using electricity as a reductant in an undivided cell [e.g., 2-(benzyloxy)-1-bromonaphthalene → (R)-2,2′-bis(benzyloxy)-1,1′-binaphthyl (72% yield (65% isolated), 93% ee) using a chiral indan-fused oxazoline and NiCl2.glyme in presence of mol. sieves]. Common metal reductants such as Mn or Zn powder resulted in significantly lower yields in the absence of elec. current under otherwise identical conditions, underscoring the enhanced reactivity provided by the combination of transition metal catalysis and electrochem. The experimental part of the paper was very detailed, including the reaction process of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7SDS of cas: 126456-43-7)
(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7) belongs to anime. Halogenation, in which one or more hydrogen atoms of an amine is replaced by a halogen atom, occurs with chlorine, bromine, and iodine, as well as with some other reagents, notably hypochlorous acid (HClO). With primary amines the reaction proceeds in two stages, producing N-chloro- and N,N-dichloro-amines, RNHCl and RNCl2, respectively. With tertiary amines, an alkyl group may be displaced by a halogen.SDS of cas: 126456-43-7
