Phenyl((trimethylsilyl)ethynyl)iodonium trifluoromethanesulfonate delivers a highly reactive phenylacetylene moiety under mild conditions. This bench-stable reagent enables efficient C–C bond formation via transition-metal-catalyzed coupling, leveraging the trimethylsilyl group for temporary stabilization and subsequent desilylation.
Phenyl((trimethylsilyl)ethynyl)iodonium trifluoromethanesulfonate serves as a stable, bench-ready electrophilic silynylation reagent enabling efficient transfer of (trimethylsilyl)ethynyl groups under mild conditions. It facilitates C–H silynylation and cross-coupling reactions with broad functional group tolerance, offering high chemoselectivity and ease of purification. Its compatibility with palladium-catalyzed processes makes it a practical tool for constructing alkynylated scaffolds in medicinal chemistry and materials science applications.
