heteroarylnitriles from the corresponding Grignard reagents (see scheme). This electrophilic cyanation is further extended to the synthesis of 2‐cyano‐1, 1′‐biaryls through a domino Grignard‐coupling/cyanation strategy.
Couplings: N‐Cyanobenzimidazole has been used in the synthesis of aryl‐ and heteroarylnitriles from the corresponding Grignard reagents (see scheme). This electrophilic cyanation is further extended to the synthesis of 2‐cyano‐1,1′‐biaryls through a domino Grignard‐coupling/cyanation strategy.
