Metathesis of cyclic alkanes catalyzed by the new surface complex [(SiO)W(Me) 5 ] affords a wide distribution of cyclic and macrocyclic alkanes. The major products with the formula C n H 2 n are the result of either a ring contraction or ring expansion of cyclooctane leading to lower unsubstituted cyclic alkanes (5≤ n ≤7) and to an unprecedented distribution of unsubstituted macrocyclic alkanes (12≤ n ≤40), respectively, identified by GC/MS and by NMR spectroscopies.
