Synthesizing Aromatic Nitriles via Cyanation

Cyanation of aromatic/heteroaromatic halides/pseudohalides is still not always a straightforward transformation, especially if the reaction needs to be scaled up. 2 Ar-X  +  Zn(CN)2  ®  2 ArCN  +  ZnX2 Workers at BMS have recently published a paper where they describe an improved protocol for this transformation1. They found that Pd2(dba)3 with XantPhos, Zn(CN)2 and i-Pr2NEt
