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.
