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

The heterogeneous tandemreactions of 2-haloanilines with isothiocyanates were achieved in DMSO using Et3N as base at 80 °C in the presence of a 3-(2-aminoethylamino)propyl-functionalized MCM-41-immobilized copper(II) complex [MCM-41-2N-CuSO4], yielding a variety of 2-aminobenzothiazoles in good to excellent yields. This heterogeneous copper catalyst exhibited higher activity than CuSO4 and can be
