and sulfur mixed tridentate palladium(0) complex [MCM-41-2N,S-Pd(0)] was prepared from 3-(2-aminoethylamino)propyltrimethoxysilane by immobilisation on MCM-41, followed by reaction with thiophene-2-carboxaldehyde and PdCl2 and then reduction with hydrazine hydrate. This phosphine-free heterogeneous palladium(0) complex was a highly active catalyst for the Suzuki reaction of aryl bromides in air and
新型 MCM-41 固定化氮硫混合三齿钯 (0) 络合物 [MCM-41-2N,S-Pd(0)] 是由 3-(2-氨基乙基氨基)丙基三甲氧基硅烷通过固定在 MCM-41 上制备的,然后通过与噻吩-2-甲醛和 PdCl2 反应,然后用水合肼还原。这种不含膦的多相钯 (0) 络合物是芳基溴在空气中的 Suzuki 反应的高活性催化剂,可以循环使用至少 8 次而不会显着损失活性。
