摘要

In the presence of a catalytic amount of Pd 2+ or Pd 0, oxidative homo-coupling of arylzinc compounds was achieved by the use of N-chlorosuccinimide (NCS) or O 2 as an oxidant. Different reaction pathways were involved in the catalytic reactions depending on the oxidants; NCS or O 2 probably oxidized I− or Pd 0 to I+ or Pd 2+, respectively. This reaction disclosed a new and facile synthetic method of biaryls from aryl halides or arenes via ...
