Metallosurfactant based Pd–Ni alloy nanoparticles as a proficient catalyst in the Mizoroki Heck coupling reaction†
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.
