Development of addtion of C-H bond to simple alkenes and alkynes by iridium catalysts

碳-氢键加成到碳-碳多重键上是一种环境友好的分子转化反应，可得到100%原子经济性的取代烯烃。在本研究中，发现阳离子铱催化剂对1，3-二羰基化合物与简单末端烯烃的加成反应显示出高的活性和选择性。在所考察的Ir催化剂中，[Ir（cod）2] SbF 6表现出最高的活性，以高产率得到相应的产物。各种末端烯烃与1，3-二酮的反应以良好至高产率产生相应的产物。

Addition of carbon-hydrogen bonds to carbon-carbon multiple bond is environmental-benign molecular transformations to afford substituted alkenes with 100% atom-economy. In the present study, cationic iridium catalysts were found to show high activity and selectivity toward the addition of 1,3-dicarbonyl compounds to simple terminal alkenes. Among Ir catalysts examined, [Ir(cod)2]SbF6 showed the highest activity to afford the corresponding products in high yields. Reaction of various terminal alkenes and 1,3-diketones produced the corresponding products in good to high yields.
