The metal catalysed reduction of compound 5 affords a mixture of syn- and anti-disubstituted cyclohexanes. Me H2 Me Me Me Me 'Me 82% cis 18% trans The reaction proceeds via the formation of a carbocation which presents a mechanism for inversion of configuration at one of the carbons O The trans-product forms because H2 can also add across the double bond in a concerted trans-fashion, albeit that this process is less favoured than cis-addition O The dynamic nature of chemical processes on surfaces allows for isomerizations to occur O After the addition of one hydrogen, the substrate can escape the surface, flip over then re-adsorb to accept a second hydrogen The metal catalysed reduction of compound 5 affords a mixture of syn- and anti-disubstituted cyclohexanes.
