ABSTRACT

By the interaction of 2-bromo-4,4,5,5-tetramethyl-2-imidazoline-3-oxide-1-oxyl (NN–Br) with tetrakis(triphenylphosphine)palladium(0) a new paramagnetic palladium-organic compound [Pd(NN)(PPh3)2Br] is synthesized. The crystal structure of its tetrahydrofuran solvate is determined by X-ray diffraction. The obtained data allow us to expect that the effective Pd–C bond eclipsing by phenyl rings deactivates the compound in a cross-coupling reaction with aryl halides and provides its high kinetic stability under normal conditions. Magnetochemical studies show the presence of weak antiferromagnetic exchange interactions between spins of paramagnetic [Pd(NN)(PPh3)2Br]. More... »
