copper(I)‐catalyzedtandemreaction of 2‐iodoanilines with isothiocyanates was achieved in hydrophobic [bmim][PF6] ionicliquid under mild conditions, generating a variety of 2‐aminobenzothiazoles in good to excellent yields. The tandemreaction that was carried out in [bmim][PF6] has some obvious advantages such as accelerated reaction rate and increased yield as compared with the reaction run in volatile
