An efficient method was developed for the desulfitativearylation of indoles with sodium sulfinates using palladium as catalyst and copper chloride dihydrate as oxidant. The directarylation occurred exclusively in the C-2 position of indoles and proceeded well for a range of different substrates.

A novel and efficient palladium‐catalyzed C2 arylation of N‐substituted indoles with 1‐aryltriazenes for the synthesis of 2‐arylindoles was developed. In the presence of BF3⋅OEt2 and palladium(II) acetate (Pd(OAc)2), N‐substituted indoles reacted with 1‐aryltriazenes in N,N‐dimethylacetamide (DMAC) to afford the corresponding aryl–indole‐type products in good to excellent yields.
