Graphical Abstract
  • above proving inefficient, palladium chemistry was subsequently considered. The vinyl bromide 24a was reported to participate in Sonagashira alkynylation chemistry; however, yields of the resultant enyne were low [20]. Therefore, we decided to investigate SuzukiMiyaura cross-coupling reaction as a

  • nanoparticles (7–10 nm in size and a palladium content of 0.03 weight% Pd on polyionic polymer). SuzukiMiyaura cross coupling reactions In our earlier work we showed that these materials are well suited for transfer hydrogenations under flow conditions [23][24]. Recently, the Suzuki–Miyaura reaction and other
  • ] these clusters exert pronounced catalytic activity in solution at very low concentrations. This view is further supported by the fact that the catalytic species operating in the present case is able to promote SuzukiMiyaura cross coupling reactions with aryl bromides while aryl chlorides are not good

The ionic nature of the resin has a positive impact on the stabilization of the Pd species which results in extended use for SuzukiMiyaura cross coupling reactions as well as Heck reactions without substantial reduction of activity even when solvents such as
