N-arylation of imidazoles, imides, amines, amides and sulfonamides with boronic acids using a recyclable Cu(OAc)2•H2O/[bmim][BF4] system

N-Arylation of imidazoles, imides, amines, amides and sulfonamides with arylboronic acids using a recyclable Cu(OAc)(2)(H2O)-H-./[bmim][BF4] system has been developed in the absence of a base or additive to afford the corresponding N-arylated products in good to excellent yields.
