Rh(I)-Catalyzed decarbonylative direct C–H bond vinylation and dienylation of arenes with readily available acrylic acid and (E)-penta-2,4-dienoic acid under chelation assistance have been developed for the first time. A significant effect of the ligand on the reactivity was observed with the bidentate phosphine ligand being optimal. This protocol was efficient under oxidant-free conditions to access synthetically valuable styrenes and 1-aryl-1,3-butadienes in high yields with a broad substrate scope and good functionality tolerance.

的Rh（我） -催化decarbonylative直接C-H键用容易得到的丙烯酸和（芳烃乙烯基化和dienylation ë）下螯合援助-戊-2,4-二烯酸已经开发了用于在第一时间。观察到配体对反应性的显着影响，其中二齿膦配体是最佳的。该方案在无氧化剂的条件下有效地以高收率获得了合成有价值的苯乙烯和1-芳基-1,3-丁二烯，具有广泛的底物范围和良好的功能耐受性。
