Technical Note:

1.Immobilized palladium heterogeneous catalyst successfully utilized in typical Suzuki and Heck reactions. The catalyst is effective for a wide range of substrates yielding coupled products in high yield. The catalyst can be simply filtered off and reused over several cycles, with no apparent loss in activity. Typical reactions using the homogeneous version of dibenzylideneaceton epalladium(O) phos phaadamantane can be found in Org. L ett.2003, 5, 6, Tetrahedron L ett.. 2004, 45, 8319 and J. Org. Chem., 2004, 69, 5082.
