“…Bougault, Cattelain and Chabrier (83,84) observed in 1939 that in the presence of Raney nickel aliphatic organic sulfur compounds under very mild conditions loose their sulfur which is replaced by hydrogen. This is furnished, as was demonstrated later (72), by the Raney nickel which contains a considerable amount of it (76,82,179,188,245,252,305,337,407,448,484). The sulfur combines with the nickel to give nickel sulfide.…”
