Abstract
We checked the catalytic activity of Ni nanoparticles prepared by pulsed-laser ablation. The transmission electron microscopy images showed that Ni metal particles would have an inhomogeneous size distribution of 5.7 (±3.8) nm. The UV absorbance spectrum exhibited metallic Ni characteristics. Ni nanoparticles appeared to exhibit the catalytic activity in the oxidative addition reaction without any activations for the preparation of 3-arylpropanenitrile from benzylchloride and bromoacetonitrile in glyme with a yield of â¼20%. We could not find this catalytic effect for the larger sizes of submicron, 3 μm, and 100 mesh Ni particles.
