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.
An electrochemically driven para-selective C(sp2)−H alkylation of electron-deficient arenes (aryl esters, aldehydes, nitriles, and ketones) has been achieved with alkyl halides (I, Br, Cl) as a couplingpartner. Undermild electrolytic conditions, a variety of alkylated arenes are obtained in one step through the formation of C(sp2)-C(sp3) bonds. Notably, the reaction enables the activation of alkyl
