Silica-supported PEI capped nanopalladium as potential catalyst in Suzuki, Heck and Sonogashira coupling reactions

We present the use of amine-functionalized silica (NH2-SiO 2) as support for palladium nanoparticles (PdNPs) and the use of heterogeneous catalysts (Pd/NH2-SiO2) for the Suzuki, Heck and Sonogashira coupling reactions. The synthesized Pd catalyst is well characterized by XRD, HRTEM, BET, SEM-EDX, FT-IR, and UV-vis spectral techniques. It exhibits efficient catalytic activity for these coupling reactions without the assistance of ligand and copper salts.

Synthesis, structure and catalysis of a NHC-Pd(II) complex based on a tetradentate mixed ligand

Bis-benzimidazolium salt (S)-2,2′-bis[2′′-(N-picolyl-benzimidazoliumyl)ethoxy]-1,1′-binaphthyl hexafluorophosphate [(S)-LH2]·(PF6)2 and its NHC palladium(ii) complex [(S)-LPd](PF6)2 (1) have been prepared and characterized. Complex 1 is formed by one tetradentate mixed ligand (S)-L and one Pd(ii) ion, in which one 15-membered ring and two 6-membered rings are present. In this complex, intramolecular π-π interactions between naphthalene rings and benzimidazole rings are observed. Additionally, the catalytic activity of complex 1 in three types of C-C coupling reactions (Suzuki-Miyaura, Heck-Mizoroki and Sonogashira reactions) was investigated. The results show that complex 1 is an effective catalyst in these coupling reactions.

Process for the preparation of alkenylbenzene derivatives or alkenylnaphthalene derivatives

Compounds of the formula I STR1 in which Z, Z1, R, m and p are as defined in patent claim 1, can be obtained in a simple and economical manner by a novel process wherein a halide of the formula II STR2 is reacted with a substituted or unsubstituted vinylbenzene or vinylnaphthalene derivative in the presence of a base and of certain palladium catalysts, such as palladium acetate. The compounds (I) or functional derivatives preparable therefrom are useful, for example, for the preparation of known dyes or fluorescent brighteners, or can be used directly as fluorescent brighteners or as scintillators.
