  • Title: Iron-catalyzed cross-coupling reactions of alkyl Grignards with aryl sulfamates and tosylates.
    Author: Agrawal T, Cook SP.
    Journal: Org Lett; 2013 Jan 04; 15(1):96-9. PubMed ID: 23244161.
    Abstract:
    The iron-catalyzed cross-coupling of aryl sulfamates and tosylates has been achieved with primary and secondary alkyl Grignards. This study of iron-catalyzed cross-coupling reactions also examines the isomerization and β-hydride elimination problems that are associated with the use of isopropyl nucleophiles. While a variety of iron sources were competent in the reaction, the use of FeF(3)•3H(2)O was critical to minimize nucleophile isomerization.
