Negishi cross coupling
The use of organozinc reagents in the Negishi (Pd- or Ni-catalyzed) cross-coupling reaction with organohalides allows for a much greater functional group tolerance than in the Kumada cross-coupling reaction. Other benefits include high reactivity, high regio- and stereoselectivity, few side reactions and little toxicity. Unlike the addition of a base in the Suzuki cross-coupling reaction, additives are not required to boost reactivity. The mechanism follows the expected oxidative addition-reductive elimination cycle.
