Abstract

Hydrogenolysis of triphenylarsine (AsPh₃) on Ni/Al₂O₃ at 172 °C and 6 bars of hydrogen occurs selectively on the nickel particles and not on the alumina support. According to the kinetic, magnetic and XRD data, the reaction of AsPh₃ with the surface Ni_s-H produces benzene and the surface organometallic fragments Ni_s-[AsPh_x]_y. Stepwise hydrogenolyis of these fragments leads progressively, with time, to the formation of arsenic 'adatoms', which migrate rapidly inside the nickel particles. The reaction is stopped after complete formation of a well defined Ni-As alloy, which has been fully characterized by X-ray diffraction.
