Abstract
Dihalogenobis(triphenylphosphine)palladium(II) complexes 1, PdX2(PPh3)2(X = Cl, Br, I), reacts reversibly with saturated and aromatic hydrocarbons RH (RH =p-xylene, toluene, benzene, n-hexane, cyclohexane), slowly at ambient temperature and rapidly on heating at 70–130 °C, to produce hydridodihalogeno(organo)bis(triphenylphosphine)-palladium(IV) complexes 2, Pd(H)(R)X2(PPh3)2; in the presence of bases complexes 2 eliminate hydrogen halide forming organobis(triphenylphosphine)palladium(II) halide 3, Pd(R)X(PPh3)2.Keywords
