Alkenylcarbene Ruthenium Arene Complexes as Initiators of Alkene Metathesis:An Enyne Creates a Catalyst that Promotes Its SelectIVe Transformation

摘要

Alkene metathesis has become a powerful reaction in organic synthesis and polymerization as it allows new approaches for making crucial C-C bonds and thus reduces the number of steps in the synthesis to natural or biologically relevant compounds.This is due to the discovery of well-defined alkylidene metal catalysts,of which those of ruthenium offer an especially good compromise between efficiency and tolerance to functional groups.
