Abstract
Oligomerization is kinetically favored in RCM reactions catalyzed by RuCl2(PCy3)(IMes)(CHPh), for a range of unhindered α,ω-dienes leading to large or medium-sized rings, even at dilutions designed to minimize intermolecular reaction. Reversible metathesis (i.e., ethenolysis) is inhibited by rapid volatilization of ethylene. At appropriately high dilutions, however, the RCM products are efficiently liberated by backbiting.
