Ni( 4-CF3 stb)3 as an alternative air-stable Ni 0 source, also performed well (Table ). Yet, the utilization of Ni(COD)(DQ) did not result in formation of 3 (Table , entry 9). Furthermore, the reaction could be carried out in DMA, which was stored on the benchtop without special precautions (Table , entry 10). Control experiments (entry 11 and 12) confirmed the requirement of both Ni and Zn for the C-N coupling to proceed.
