Ni-catalyzed Sonogashira coupling of nonactivated, beta-H-containing alkyl halides, including chlorides, is reported. The coupling is tolerant to a wide range of functional groups, including ether, ester, amide, nitrile, keto, heterocycle, acetal, and aryl halide, in both coupling partners. The coupling can be selective for a specific C-X bond (X = I, Br, Cl) and allows for orthogonal functionalization
据报道,Ni 催化的 Sonogashira 偶联未活化的、含 β-H 的烷基卤化物,包括氯化物。偶联可以耐受多种官能团,包括醚、酯、酰胺、腈、酮、杂环、乙缩醛和芳基卤化物,在两种偶联伙伴中。偶联可以对特定的 CX 键 (X = I, Br, Cl) 具有选择性,并允许具有多个反应位点的卤代烷正交官能化。
