Allylmalonate as an Activator Subunit for the Initiation of Relay Ring-Closing Metathesis Reactions

Passing the baton: The relay ring‐closing metathesis (RRCM) reaction of complex polyenes 1 has been studied. Several relay subunits (T) were examined and many did not sufficiently activate the RRCM. An allylmalonate‐containing relay subunit solved this problem, and efficiently lead to the diene 2. T...
