Substituent-Dependent Selective Replacement of Alkyne Moieties of Zirconacyclopentadienes via C-C Bond Cleavage Reaction
Replacement of an alkyne moiety of zirconacyclopentadienes via β,β′-carbon-carbon bond cleavage was highly dependent on their substituents. Complete differentiation between diphenylacetylene and 4-octyne in the reaction with butyronitrile was demonstrated.
