Ring-opening metathesis polymerisation of norbornene by OsO4: evidence for a transient oxametallacyclobutane
Abstract
When norbornene is treated with a catalytic amount of OsO4 at 60°C, a substantial yield of ring-opened metathesis polymer is obtained among the products; this result provides strong evidence that transient oxometallacyclobutane species are formed using this alkene oxidation reagent.
