Heterogenized gold(I), gold(III), and Palladium(II) complexes for C-C bond reactions

Recycling, of heterogenized gold(I), gold(III), and palladium(II) complexes Could be achieved for Suzuki and Sonogashira cross-coupling reaction between iodo benzene and arylboronic acids or alkynes. Au(I) and Pd(II) afford selectively nonsymmetrical biaryl compounds, while gold(III) complexes can only catalyze the arylboronic or alkynes homocoupling. Recycling occurs without loss of the catalytic activity after several reaction cycles.
