Palladium nanoparticles (size=1.6±0.3 nm) stabilized by a polyethylene glycol containing triazolyl rings, synthesized by click reaction in water, are efficient catalysts for the Suzuki–Miyaura coupling of bromoarenes in aqueous ethanol and the borohydride reduction of 4‐nitrophenol in water. Turnover numbers (TONs) reach 99,000 and turnover frequencies (TOFs) are up to 198,000 h −1 for the CC cross coupling reactions in water/ethanol.
