- The reaction of PdCl2 dispersed in tetra-n-butylammonium bromide with tributyl amine at 120 ℃ under argon leads to
stable isolable nanometric particles. X-ray diffraction analysis of the material indicated that it is constituted of Pd(0).
Transmission electron microscopy analysis of the particles dispersed in acetone shows the mean particle size distribution
(4 ± 1 nm). The isolated palladium nanoparticles can be dispersed in an ionic liquid or in methanol or used in solventless
condition for selective hydrogenation of 2-hexyne under mild reaction conditions(0.2 MPa and 20 ℃). The commercial
variety of the Lindlar catalyst was also studied for comparative investigations.
