Facile generation and morphology of Pd nanoparticles from palladacycles and carbon monoxide

Treatment of PdCys or palladium salts with carbon monoxide (1 atm) in DMF or toluene at room temperature results in a solution of palladium nanoparticles whose morphology depends on the PdCy or palladium salt. Unusual triangular shaped 2–12 nm nanoparticles result from PdCys 1 and 3.
