Abstract
Rh COT in the act: a Ni(0)-catalyzed [2+2+2+2] cycloaddition provides a high-yielding, scalable synthesis of the ligand dinaphtho[a,e]cyclooctatetraene (dnCOT). dnCOT complexation with Rh(I) gives [Rh(dnCOT)(MeCN)(2)]SbF(6), an excellent catalyst for [5+2] cycloadditions of vinylcyclopropanes and π-systems with impressive functional group compatibility.
摘要
Rh COT 在反应中：Ni(0)催化的 [2+2+2+2] 环加成反应提供了高产率、可规模化的配体二萘并[a,e]环辛四烯 (dnCOT) 的合成方法。dnCOT 与 Rh(I) 配位得到 [Rh(dnCOT)(MeCN)(2)]SbF(6)，这是一种用于乙烯基环丙烷和 π-体系的 [5+2] 环加成反应的优秀催化剂，具有令人印象深刻的官能团兼容性。
