        In the presence of a Ni catalyst precipitated on Al(OH)3, cyclohexane (I) in H2 atmospheric at 330-350 undergoes a peculiar conversion with the formation of complex hydrocarbons.  Along with a dehydrogenation of (I) to C6H6 a deep-seated cleavage takes place with the formation of free CH2 radicals.  These are, in part, reduced to CH4 and in part combine with the C6H6 and the unaltered (I) to form toluene, xylene, methylcyclohexane, and dimethylcyclohexane.
