The preparation of NiCRA (NaH-B:ONa-Ni(OAc) ) in the oresence of PPh3 leads to a reagent (termed NiCRA-PPh3) which is shown $ o be one of the most efflclent Ni containing reagents reported so far for the homocoupling of heteroaromatic halides. Symmetrical couDling of aryl halides may be performed wi
