Asymmetric Cross-Coupling of Non-Activated Secondary Alkyl Halides†
I thank the Fonds der Chemischen Industrie, the Alfried Krupp von Bohlen und Halbach Foundation, and the Deutsche Forschungsgemeinschaft for generous financial support.
Graphical Abstract
A new star is born: First reports on asymmetric cross-coupling reactions of racemic activated and non-activated secondary alkyl halides highlight the particular suitability of nickel catalysts for these reactions. Impressively high enantioselectivities were observed for Negishi, Hiyama, and Suzuki–Miyaura cross-coupling reactions (see scheme). The results can be expected to change retrosynthetic thinking.
