first example of In(III)-catalyzed selective 6-exo-dig hydroarylation of o-propargylbiaryls and their subsequent double-bond migration to obtain functionalized phenanthrenes. Electron-rich biaryl substrates undergo hydroarylation more effectively, and the substrates with various types of substituents on the alkyne can also be smoothly and selectively converted to phenanthrenes.
本文介绍了In(III)催化邻炔丙基联芳基的选择性6- exo - dig加氢芳基化反应及其随后的双键迁移以获得官能化菲的第一个实例。富电子的联芳基底物更有效地进行氢芳基化,并且在炔烃上具有各种取代基的底物也可以平稳且选择性地转化为菲。
