black precipitate reveal that Pdnanoparticles are formed during the reactions and are stabilized by the carboxylic-functionalized thiourea ligands. Eight precatalysts containing carboxylic-functionalized thiourea ligands are prepared and their activities and recyclability are evaluated in aerobic aqueous Suzuki–Miyaura reactions. A bulky monothiourea–Pd complex, functionalized with four carboxylic groups

The Suzuki–Miyaura reaction of aryl bromides using 3-(2-aminoethylamino)propyl-functionalized MCM-41-immobilized palladium(II) complex [MCM-41-2N-Pd(II)] as an efficient heterogeneous catalyst is described. Developed catalyticsystem is found to be effective for the Suzuki–Miyaura reaction of aryl bromides with arylboronic acids providing good to excellent yield of the desired products. This heterogeneous

and sulfur mixed tridentate palladium(0) complex [MCM-41-2N,S-Pd(0)] was prepared from 3-(2-aminoethylamino)propyltrimethoxysilane by immobilisation on MCM-41, followed by reaction with thiophene-2-carboxaldehyde and PdCl2 and then reduction with hydrazine hydrate. This phosphine-free heterogeneous palladium(0) complex was a highly active catalyst for the Suzukireaction of aryl bromides in air and

A new indolylphosphine WK‐phos has been synthesized for Pd‐catalyzed Suzuki–Miyauracoupling of (hetero)aryl chlorides with (alkyl)arylboronicacids. The catalyst system with this new ligand was found to be highly effective in facilitating the reaction even at catalyst loading levels in the parts per million range (e.g. 10 ppm).

This work examines how N‐donor bridged spacer ligands affect N‐heterocyclic carbene (NHC) palladium complexescatalyticactivities for Suzuki coupling reaction. Different degrees of structural flexibility binuclear NHC palladium complexes were synthesized. The more flexible nitrogen‐based alkyl chain ligand shows similar performance with cycloamine counterparts in the Suzuki coupling reaction. Suzuki
