摘要
Asymmetric copper chemistry ... done heterogeneously? It's doable: Copper-incharcoal (Cu/C) is introduced as an easily prepared catalyst that is readily converted in situ into a nonracemically ligated form of copper hydride that effects asymmetric hydrosilylations. DTBM = 3,5-di-tert-butyl-4- methoxydiphenylphosphinyl. (Figure Presented) © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
