Highly efficient and recyclable water-soluble fullerene-supported PdCl(2) nanocatalyst in Suzuki–Miyaura cross-coupling reaction

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.
