Nano-palladium @ superparamagnetic Fe3O4 as catalyst for Heck coupling reaction(钯纳米粒子@超顺磁性Fe3O4催化的Heck偶联反应)
利用Fe3O4溶胶的正电荷特性，将络负离子通过静电作用吸附在Fe3O4胶体粒子表面，以抗坏血酸(Vc)进一步将其还原，即得到负载有Pd金属团簇的Fe3O4胶体粒子（Pd0@Fe3O4）.该超顺磁性Fe3O4载体负载的纳米Pd对Heck反应表现出良好的催化活性，且反应完毕后可简单地通过永久磁铁将催化剂从反应体系中分离，循环使用，研究表明，该催化剂在循环使用5次后反应活性没有明显下降，并对多种卤代芳烃的Heck偶联反应表现出优异的催化活性....
