Iron-catalyzed cross-coupling of aryltrimethylammonium triflates and alkyl Grignard reagents
摘要:
Fe(acac)(3) effectively catalyzes reaction of aryltrimethylammonium triflates with beta-hydrogen-containing primary or secondary alkyl Grignard reagents in a mixed solvent of THF and NMP at room temperature. A series of functional groups are tolerated under the reaction conditions. (c) 2013 Elsevier Ltd. All rights reserved.
A revisit of organoaluminumreagents for cross-coupling reactions has opened up several types of C–C bond formation protocols through cleavage of phenolic/alcoholic C–O and C–F and ammonium C–N bonds. Catalyzed by the commercially available NiCl2(PCy3)2 catalyst, these reactions proceed smoothly with a wide range of substrates and broad functional group compatibility, providing a versatile methodology
