Latent and Switchable Olefin Metathesis Catalysts

Authors


Abstract

Summary: Many latent olefin metathesis initiators have been described in the recent years. In this symposium manuscript, we present our contribution to the field, based on the use of different heteroatoms; namely sulfur, nitrogen, phosphorous and selenium; as chelators in ruthenium bidentate benzylidenes. The steric and electronic parameters were thoroughly studied and used in order to prepare not only latent pre-catalysts but also thermo- and photo-switchable systems – effectively granting control over both reaction initiation and interruption.
