Nickel-catalyzedSuzuki–Miyaura coupling of heteroaryl ethers with arylboronicacids was described. Selective activation of the phenol C–O bonds was achieved by converting them into the corresponding aryl 2,4-dimethoxy-1,3,5-triazine-6-yl ethers, in which aryl C–O bond could be selectively cleaved with inexpensive, air-stable NiCl2(dppf) as a catalyst. Coupling of these readily accessible heteroaryl
