The decomposition of a series of ruthenium metathesis catalysts has been examined using methylidene species as model complexes.
The great popularity of this methodology is mainly related to the development of well-defined ruthenium alkylidene catalysts with high air and moisture stability and functional group.
The ruthenium catalyst is readily synthesized from common reagents via simple reaction steps and is stable in the presence of water which should promote its application in precisely stereo.
