A highly efficient, operationally simple and green catalytic approach involving Pd–Ni alloy nanoparticles (NPs) has been developed using microwaves (MWs) as an energy source and water–ethanol as a solvent system. Metallosurfactants were synthesized and used as precursors to fabricate Pd–Ni alloy NPs with a good control over the size and morphology. Surfactant capped zerovalent Pd–Ni alloy NPs were fabricated in the metallomicellar cores by a two-phase reduction method. The synthesized NPs exhibited the highest catalytic efficiency for the stereoselective Mizoroki Heck coupling featuring short reaction time, mild reaction conditions, wide substrate scope, preclusion of toxic organic solvents, easy recovery and recyclability of the catalyst.

基于金属表面活性剂的Pd-Ni合金纳米颗粒可作为Mizoroki Heck偶联反应的有效催化剂

已经开发了一种高效，操作简单且绿色的催化方法，该方法涉及使用Pd-Ni合金纳米颗粒（NPs）作为能源，而水-乙醇作为溶剂体系。合成了金属表面活性剂，并用作制造Pd-Ni合金NP的前体，并能很好地控制其尺寸和形貌。表面活性剂封端的零价Pd-Ni合金纳米粒子是通过两相还原法在金属硅铁心中制备的。合成的NPs对立体选择性Mizoroki Heck偶联反应表现出最高的催化效率，具有反应时间短，反应条件温和，底物范围广，有毒有机溶剂被排除，催化剂易于回收和可回收利用的特点。
