Реферат: An efficient method for the C(2)−H arylation of (benz)imidazoles and (benz)oxazoles with aryl chlorides and aryl bromides under Ni/NHC catalysis has been developed. The main benefit of the method is the in situ generation of active Ni/NHC complexes from the air-tolerant bench-stable precursors NiCl2Py2, IMes⋅HCl, and potassium tert-butoxide, which plays a dual role as base and Ni(II) to Ni(0) reductant. The approach represents a user-friendly alternative for procedures relying on the use of toxic phosphine ligands or unstable air-sensitive Ni(cod)2. The concept highlighted in the present study shows that mapping a competitive picture of catalyst dynamics and revealing the competitive processes towards the destruction and stabilization of catalytically active species enables a highly efficient catalytic system to be built under simple conditions.
