    • Note
    • The positive effect of TBAB can be rationalized by two factors: i)stabilization of leached palladium species against agglomeration preventing thus their deactivation and ii)the oxidative addition of arylbromide to palladium(0) can be facilitated by bromide ions which provide adequate electron density to the metal.
