N-heterocyclic carbene coordinated ruthenium benzylidene complex [(H2IMes)(PCy3)(Cl)2RuCHPh], a highly
active olefin metathesis catalyst, is known to convert into a very
fast initiator in the presence of pyridine or 3-bromopyridine. Computational
studies presented in this work reveal the mechanistic basis of this
phenomenon. Depending on the size of the olefin, the reaction follows
either a dissociative or associative mechanism.
