Abstract
Aromatic nitriles possess versatile utilities and are indispensible not only in organic synthesis but also in the chemical industry.(1) In fact, the nitrile group is an important precursor for various functional groups such as aldehydes, amines, amidines, tetrazoles, amides, and their carboxyl derivatives.(2) In addition, biphenyls represent a key structural motif in a large number of compounds used as pharmaceuticals, agrochemicals, dyes, chiral ligands for metal catalysts, liquid ...
