  • Title: Palladium-indolylphosphine-catalyzed Hiyama cross-coupling of aryl mesylates.
    Author: So CM, Lee HW, Lau CP, Kwong FY.
    Journal: Org Lett; 2009 Jan 15; 11(2):317-20. PubMed ID: 19099495.
    Abstract:
    Aryl mesylates are found to be applicable as electrophiles in organosilicon-mediated coupling reactions. The catalyst system comprising 2 mol % of Pd(OAc)(2) and CM-phos supporting ligand is highly effective in catalyzing Hiyama cross-coupling of various aryl and heteroaryl mesylates. Interesting acid additive effects show that the presence of 0.25-0.50 equiv of acetic acid efficiently suppresses the mesylate decomposition and generally promotes the coupling product yields.
