【摘要】 <正>Recently,the less expensive ruthenium（Ⅱ）complex has emerged into the field of chelationassisted oxidative olefination of arenes as a useful catalyst.Several groups have shown that use of the[{RuL₂（p-cymene）}₂]（L=Cl or OAc）catalyst allows the oxidative coupling by using copper acetate as oxidant.¹Direct C2 alkenylation of indole via transition-metal catalyzed C-H bond activation is still a challenge due to the electrophilic nature of the reaction as well as the higher C-H nucleophilic更多还原
