Abstract

Four different triazolylbiferrocenyl-containing polymers were used for the stabilization of palladium nanoparticles (PdNPs) upon reducing triazole-coordinated Pd(II) both in organic solvents and in water. The resulting PdNPs were active in the Suzuki–Miyaura coupling of bromoaromatics even with down to only 20 ppm of Pd. The comparison between the four different polymer-stabilized PdNPs allows concluding that a flexible polyethylene glycol moiety in the linear triazolylbiferrocenyl polymer permits a better stabilization of the PdNPs than polymers containing triazolylbiferrocenyl side chains with a rigid styrene or succinimide moieties.
