General, Straightforward, and Atom-Economical Synthesis of Vinyl Triflimides.

Vinyltriflimides were only accessible recently and their chemistry is yet to bediscovered. Herein, we describe a general, straightforward and atom-economicalsynthesis of these materials from alkynes and triflimide. A vast array ofterminal and internal alkynes with broad spectrum of functionalities could beemployed to generate various di- and trisubstituted vinyl triflimidesregiospecifically with high to specific stereoselectivity. Moreover, theprotocol could be conducted on gram scale using terminal and internal alkynes.Preliminarily attempts to probe the unknown reactivity of vinyl triflimidesrevealed part of its chemical properties.
