1-(烯丙氧基)-2-(1-芳基乙烯基)苯和1-(1-芳基乙烯基)-2-(乙烯基氧基)苯的新型可见光介导二氟烷基化合成双-二氟烷基苯并氧杂环庚烷和2 H-开发了色烯。该方法具有反应条件温和、区域选择性好、底物范围广、官能团相容性好、后期修饰等特点。初步机理研究表明,CF 2 CO 2 Et 自由基的生成更容易与芳基的双键发生反应。
A Rh(III)-catalyzed one-pot reaction of N-phenoxyacetamides, ketones, and hydrazines for a facile access to disubstituted and trisubstituted ethylenes is reported. In this method, various ketones are transformed into donor–donor diazo compounds, which engage in insertion with N-phenoxyacetamides, following β-H elimination under Rh(III) catalysis to generate (E)-polyaryl-substituted olefins.

An efficient cobalt(III)‐catalyzed intramolecular cross‐dehydrogenative C−H/N−H coupling of ortho‐alkenylanilines has been developed utilizing O2 as a terminal oxidant. The developed reaction tolerates various reactive functional groups and allows the synthesis of diverse indole derivatives in good to excellent yields. The method was successfully extended to the synthesis of benzofurans through the
