An ion-beam apparatus is employed to study the reaction of singly charged cobalt positive ions with cyclopropane, cyclobutane, cyclopentane, and cyclohexane. In all cases, ring cleavage reactions are observed. These processes find analogy with the decompositions of solution-phase metallacycles by C-C bond cleavage. In all systems but cyclopropane, dehydrogenation of the cycloalkane is also observed. Multiple dehydrogenation occurs with cyclopentane (yielding Co(C/sub 5/H/sub 6/)/sup +/) and cyclohexae (yielding Co(Ct/sub 6/H/sub 8/)/sup +/ and Co(C/sub 6/H/sub 6/)/sup +/). The present results are contrasted with the reactions of Co/sup +/ with the isomeric alkenes.
