The presence of CH//2 species on a carbon-deposited cobalt catalyst is demonstrated by the disproportionate formation of CH//2D//2 in the reaction with D//2. Hydrogenation of a **1**3C-deposited Co/C catalyst at 430 degree C yielded methane and a trace amount of ethylene, and it was found that the **1**3C content was substantially different in methane (31%) from that in ethylene (83%). If ethylene was brought into contact with the **1**3C-deposited Co/C catalyst at 180 degree C, (**1**3C//1)-propene was predominantly formed via a homologation reaction.
