We report herein a simple, efficient strategy to access diverse end-functionalized polymers from a livingring-openingmetathesis polymerization process using diazoacetates as a new terminating agent. Such a terminating process occurs via a C═C bond-forming reaction between the chain-end ruthenium carbenes and the diazoacetates, resulting in the rapid construction of a unique, α,β-unsaturated carbonyl
