Chain-length-dependent reactivity of alkenyl phosphates in ruthenium-catalyzed cross-metathesis

Chem. Commun., 2026, Advance Article DOI: 10.1039/D5CC05790F, Communication Apicha Pontavatchai, Kevin Schwedtmann, Philipp Royla, Kai Schwedtmann, Tossapol Khamnaen, Uwe Schwarzenbolz, Thomas Henle, Ekasith Somsook, Jan J. Weigand Chain length controls fate in Ru-catalyzed cross-metathesis of alkenyl phosphates: vinyl triggers Ru-carbide via proton-coupled phosphate elimination, whereas allyl/butenyl tethers restore productive CM. DFT rationalizes the switch.
