Olefination of carbon–heteroatom double bonds is a powerful approach to access highly functionalized olefins. An approach is reported here that uses air-stable and commercially available rutheniumalkylidenes to promote C=N/olefin ring closure. The enabling strategy for this reaction is the use of hydrazones and oximes as readily accessible substrates that preferentially react with ruthenium alkylidenes
