Demethylation of Coordinated Hexamethylbenzene. Carbon−Carbon Bond Activation during Ruthenium-Mediated [3 + 2] Allyl Alkyne Cycloaddition Reactions

Demethylation of Coordinated Hexamethylbenzene. Carbon−Carbon Bond Activation during Ruthenium-Mediated [3 + 2] Allyl Alkyne Cycloaddition Reactions

The demethylation of coordinated hexamethylbenzene is integrated into [3 + 2] allyl/alkyne cycloaddition reactions mediated by (η6-hexamethylbenzene)Ru(η3-allyl)OTf. The reaction proceeds in high yield at or below room temperature and yields methane and (η6-pentamethylbenzene)ruthenium(1,2-dialkylcy...

Zusammenfassung:The demethylation of coordinated hexamethylbenzene is integrated into [3 + 2] allyl/alkyne cycloaddition reactions mediated by (η6-hexamethylbenzene)Ru(η3-allyl)OTf. The reaction proceeds in high yield at or below room temperature and yields methane and (η6-pentamethylbenzene)ruthenium(1,2-dialkylcyclopentadienyl)+OTf- complexes exclusively. Cycloaddition with carbon−carbon bond activation is general for a range of disubstituted alkynes.
