In 2020, Nocera stated that the coupling of heteroaryl bromides was not feasible as a result of the unproductive substrate coordination, resulting in coordinatively saturated Ni I species. In contrast to these precedent, the use of NiBr2(dme) seemed feasible under our optimized conditions when using 1 (Table , entry 5). For this reason, we decided to benchmark the use of NiBr2(dme) and Ni( 4-tBu stb)3 with other heteroaryl bromides. In agreement with Nocera, the yields were substantially decreased when using NiBr2(dme). For example, in the case of 6 the yield with Ni II plummeted from 84% to 45% (Fig. ).
