Postmetalation Ligand Modification on the Periphery of a Diruthenium Compound: Toward Novel Metallayne Scaffoldings
摘要:
A diruthenium compound bearing a peripheral iodo substituent cross-couples with acetylenes under Sonogashira conditions to yield a novel family of diruthenium compounds bearing a peripheral alkyne functionality, which can be further functionalized at the axial positions via a reaction with lithiated butadiynyl.
