Functionalization of aryl C–Y bonds: cross-coupling vs group insertion. a functionalization of aromatic C–Y bonds; b conventional functionalization of aryl C–N bonds (nitrogen lost); c functional group insertion into aryl C–N bonds (nitrogen kept). FG functional group, TM transition metal, Ar aryl group. FG in pink and in a cyan rectangle, TM in blue, and Y, N, nitrogen, NH2, amines in purple mean emphasis. The different colors used here is for the convenience of reading
