  • Title: Advantageous use of tBu2P-N=P(iBuNCH2CH2)3N in the Hiyama coupling of aryl bromides and chlorides.
    Author: Raders SM, Kingston JV, Verkade JG.
    Journal: J Org Chem; 2010 Mar 05; 75(5):1744-7. PubMed ID: 20121173.
    Abstract:
    An efficient catalytic route to biaryls by employing (generally) only 0.25 mol % of Pd(OAc)(2) and 0.5 mol % of 1 in the Hiyama coupling reaction is reported. High yields for electron-rich, -neutral, and -deficient aryl chlorides are obtained. A variety of phenylsiloxanes undergo coupling with aryl bromides and chlorides with low Pd(OAc)(2)/1 loadings.
