An efficient protocol has been developed for the preparation of 2‐aminobenzothiazoles via a copper(I)‐catalyzed tandem reaction of 2‐iodoanilines with isothiocyanates at very low catalyst loadings [typically 50 ppm of copper(I) iodide (CuI)]. A variety of 2‐iodoanilines could be cross‐coupled with isothiocyanates, affording 2‐aminobenzothiazoles in moderate to good yields (49–93%) under the given conditions

A copperiminopyridinecomplex has been immobilized on to a metal–organic framework (MOF) through postsyntheticmodification of IRMOF‐3. The modified MOFs were fully demonstrated by using a variety of methods, and the structural integrity of the modified MOFs has been confirmed by powder X‐ray diffraction (XRD). Furthermore, it was shown that the modified IRMOF‐3 can act as an efficient solid catalyst
