聚γ-(β-甲硒基)丙基硅氧烷钯(Ⅱ)配合物的合成及其催化酰胺化性能

Synthesis of Poly-r-(β-methlseleno)Propylsiloxame Palladium(Ⅱ) Complex and Its Catalytic Property for Amidation of Aryl Halide

γ -氯丙基三乙氧基硅烷依次进行气相法二氧化硅固载化 ,甲基硒钠硒化 ,再与氯化钯反应 ,合成聚γ - (β -甲硒基 )丙基硅氧烷钯 (Ⅱ )配合物 ,研究其催化物芳基卤化物的酰胺化性能 .

A fume silica-bound poly-γ-(β-methylseleno)propylsiloxane Palladium(Ⅱ)complex was synthesized from γ-(β-methylseleno)propylsiloxame and fume silica via hydrolysis, followed by tremeated will palladium chloride in acetone The title complex is an efficient catalyst for Heck carbonylation of aryl halides with anitine and can be used repeatedly without serious loss of activity
