One-Pot Synthesis of Ferrocenyl Ketones Containing Biaryls and 6-Aryl-2-ferrocenylquinolines via Ir/Pd-Cocatalyzed α-Alkylation/Suzuki Reaction
摘要:
An efficient PPh3-cyclometalated iridium(III) benzo[h]quinoline hydride 1/Pd(OAc)(2)-cocatalyzed three-component alpha-alkylation/Suzulci reaction has been developed. The three-component reaction of 4-bromobenzyl alcohol, acetylferrocene, and arylboronic acids gives ferrocenyl ketones containing biaryls in moderate to good yields. This method was successfully applied to a one-pot synthesis of 6-aryl-2-ferrocenyl quinolines, using (2-amino-5-bromophenyl)methanol instead of 4-bromobenzyl alcohol.
