Synthesis of Functionalized Aryliron Complexes by Palladium-Catalyzed Transmetalation between [CpFe(CO)2I] and Arylzinc or Arylboron Reagents

Transmetalation between [CpFe(CO) 2 I] and arylzinc reagents or arylboronic acids under palladium catalysis yields the corresponding aryliron complexes [CpFe(CO) 2 Ar]. The reactions offer easy and reliable accesses to a variety of [CpFe(CO) 2 Ar] species bearing a functionalized aryl group.
