摘要：

A new indole-tolerant oxidation condition for the synthesis of 1,2-diketone derivatives from the corresponding 1,2-diarylalkynes was described. By screening a series of oxidation systems on alkynes linked with indole and different substituted aromatic ring, the DMSO/PdCl2/CuCl2 system afforded moderate to good yields despite the existence of electron-rich indole ring.
