Transition-metal-catalyzed cross-coupling of electrophile containing multiple potential coupling sites is often challenging. A straightforward cross-electrophile coupling of aryl iodides and aryltriazenes via photoredox/palladium dual catalysis was developed. The reaction was carried out by using Pd(OAc) 2 as catalyst, Cu(OAc) 2 as promoter, aryltriazenes as arylation reagents and base, various biaryl compounds were afforded under mild conditions. This synergistic method features photoredox/Pd dual catalysis, easily available substrates, gram scale synthesis, synthetic applications, mild, neutral and base-free conditions.
