Precursor Decomposition

This paper describes the synthesis of Pd-containing catalysts based on nonfunctionalized hypercrosslinked polystyrene via impregnation with Pd acetate. Developed Pd nanoparticulate catalyst allowed achieving conversion of aryl halide up to 90% in Suzuki cross-coupling reaction under mild conditions and at the absence of phase-transfer agents. During the selective hydrogenation of triple C-C bond of 2-methyl-3-butyn-2-ol, up to 96% selectivity with respect to corresponding olefinic alcohol was found at 95% conversion. The influences of the procedure of catalyst synthesis like precursor decomposition and reductive activation method on Pd nanoparticle formation are discussed.

Nanoparticle Catalyst

A novel Pd-nanoparticle-catalyst supported on chitosan-pyridine-modified carbon nanotube (CNT) was prepared. The obtained Pd-catalytic platform (Pd@CS-Py@CNT) was fully characterized and employed to the Suzuki–Miyaura coupling reaction as a heterogeneous catalyst, showing an excellent catalytic activity in aqueous media in the absence of phase transfer agents. Moreover, the easy recoverability and reusability of the catalytic system after a simple manipulation is a great benefit.
