Abstract
Thermolytic decomposition pathways were studied for several ruthenium carbe ne-based olefin metathesis catalysts. Substituted carbenes were found to de compose through bimolecular pathways while the unsubstituted carbene was fo und to decomposed unimolecularly. Implications for ring-closing metathesis are discussed, and the longevity of several ruthenium-based catalysts are c ompared.
