Synthesis of Functionalized Aryliron Complexes by Palladium-Catalyzed Transmetalation between [CpFe(CO)2I] and Arylzinc or Arylboron Reagents
摘要:
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.
Arylation of Styrenes with Aryliron Complexes [CpFe(CO)2Ar]
摘要:
Treatment of aryliron complexes [CpFe(CO)(2)Ar] with styrenes in boiling xylene affords the corresponding stilbenes. The aryliron complexes, which become active upon heating, serve as arylating agents in the reaction.

Treatment of aryliron complexes [CpFe(CO)2Ar] with organolithium reagents RLi in THF affords the corresponding ketones RCOAr. The reaction, wherein the aryliron complexes serve as arylcarbonyl cationequivalents, would begin with nucleophilic addition of RLi to one of the carbonyl ligands to form acyliron [CpFe(CO)(RCO)Ar] without lithiation of the Cp ring.
