Allylic C-H functionalization catalysed by group 9 Cp* transition-metal complexes has recently gained significant attention. These reactions have expanded allylic C-H functionalization to include di- and trisubstituted olefins, and a broad range of coupling partners. More specifically, several catalytic C-N, C-O, and C-C bond forming allylic C-H functionalization reactions have been reported, proceeding via MCp*-π-allyl intermediates. Herein we present an overview of these reactions by mechanistic paradigm. We also place this information in context of recent advances, as well as, limitations that remain for this class of reactions.
近年来，由第 9 族 Cp过渡金属配合物催化的烯丙基 C-H 官能化反应引起了广泛关注。这些反应将烯丙基 C-H 官能化扩展到包括二取代和三取代烯烃以及广泛的偶联伙伴。更具体地说，已经报道了几种催化的 C-N、C-O 和 C-C 键形成的烯丙基 C-H 官能化反应，它们通过 MCp-π-烯丙基中间体进行。本文通过机理范例对这些反应进行了概述。我们还将这些信息置于该类反应的最新进展以及仍然存在的局限性的背景下。
