Highly efficient and recyclable water-soluble fullerene-supported PdCl2 nanocatalyst in Suzuki–Miyaura cross-coupling reaction

摘要

A water-soluble fullerene-supported PdCl _(2) nanocatalyst [C _(60) -TEG _(S) /PdCl _(2) ] was prepared by coordination of water-soluble fullerene nanoparticles with palladium chloride. In pure water, the catalytic activity of nanocatalyst [C _(60) -TEG _(S) /PdCl _(2) ] for Suzuki–Miyaura cross-coupling reaction was investigated under different reaction conditions. The results showed that biphenyl compounds could be synthesized in high yields at room temperature using 0.01 mol% of [C _(60) -TEG _(S) /PdCl _(2) ] as the catalyst and K _(2) CO _(3) as the base with the reaction time of 4 h. The catalyst was recycled five times, and the yield clearly did not decrease.
