Functionalized imidazolium salt: an efficient catalyst for Buchwald–Hartwig type C–N cross-coupling of (hetero)aryl chlorides/bromides with amines under solvent-, inert gas-, and base-free ambience

The intermingling of novel imidazolium salt (HL 1 -Br) and Cu(OAc) 2 has been marked down as a highly efficient catalytic system for Buchwald–Hartwig-type C–N coupling of a variety of amines with (hetero) aryl bromides/chlorides.
