A very highly purified mixture of CO and H₂ (1:2) was allowed to react over a Ni-Co-Al catalyst in the presence of C₆H₆(I) at 190°; small quantities of toluene (II) and xylene (?) were formed (detected as nitrotoluene and nitroxylene (?), respectively. The formation of (II) was explained through the action upon (I) of methylene radicals, intermediately formed during the contact hydrogenation of CO.
