pressure of carbon monoxide has been achieved in anisole at 80 °C in the presence of a catalytic amount of an MCM-41-supported bidentate phosphane palladium(II) complex (MCM-41-2P-PdII), yielding unsymmetrical biaryl ketones in good-to-high yields. This polymeric palladium catalyst exhibited higher activity and selectivity than [PdCl2(PPh3)2] and can be reused at least 10 times without any decrease in activity
在催化量的 MCM-41 负载的双齿磷烷钯存在下,在 80°C 下,在一氧化碳的大气压下,芳基硼酸与芳基碘化物的第一个非均相羰基化 Suzuki-Miyaura 交叉偶联反应已在苯甲醚中实现(II) 复合物 (MCM-41-2P-PdII),以从良到高的产率产生不对称的联芳基酮。这种聚合钯催化剂表现出比 [PdCl2(PPh3)2] 更高的活性和选择性,并且可以重复使用至少 10 次而不会降低活性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
