non-symmetric azobenzene derivatives by an unprecedented C(sp2)−N(sp2) cross-coupling is presented. N-Aryl-N′-silyldiazenes are employed as diazenyl anion equivalents that can be selectively coupled under palladium catalysis with a large array of (hetero)aryl bromides in high yields. The functional-group tolerance on either (hetero)aryl ring is excellent.
