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

摘要

A water-soluble fullerene-supported PdCl2 nanocatalyst [C-60-TEGS/PdCl2] was prepared by coordination of water-soluble fullerene nanoparticles with palladium chloride. In pure water, the catalytic activity of nanocatalyst [C-60-TEGS/PdCl2] 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-TEGS/PdCl2] as the catalyst and K2CO3 as the base with the reaction time of 4 h. The catalyst was recycled five times, and the yield clearly did not decrease.
