Are you hoping to find 'metathesis chemistry'? You will find all of the details here.
Alkene metathesis is AN organic reaction that entails the redistribution of fragments of alkenes (olefins) aside the scission and regeneration of carbon-carbon double bonds. Because of the relational simplicity of alkene metathesis, it ofttimes creates fewer unwanted by-products and wild wastes than secondary organic reactions.Organic Chemical science Portal: RSC ontology ID:
