  • Title: Pd(PPh3)4-PEG 400 catalyzed protocol for the atom-efficient Stille cross-coupling reaction of organotin with aryl bromides.
    Author: Zhou WJ, Wang KH, Wang JX.
    Journal: J Org Chem; 2009 Aug 07; 74(15):5599-602. PubMed ID: 19552378.
    Abstract:
    Aryl bromides (4 equiv) were coupled efficiently with organotin (1 equiv) in an atom-efficient way using the tetra(triphenylphosphine)palladium/polyethylene glycol 400 (Pd(PPh3)4/PEG 400) catalytic system in the presence of sodium acetate (NaOAc) as base at 100 degrees C, providing excellent yields of the corresponding functionalized biaryls in short reaction times.
