Prescursors for and synthesis of mono- and difunctionalized acetylenes and difunctional 1,3-diynes

Precursors and methods for the synthesis of mono- and difunctionalized acetylenes are described. The invention includes novel tricoordinate iodonium transfer reagents and novel alkynyldi(phenyliodonium) salts, both of which are precursors for the function

Novel classes of alkynyliodonium salts and their applications: The synthesis of substituted 1,3-diynyliodonium triflates, R-C≡C-C≡C-I+-Ph -OTf, and their reaction with triphenylphosphine

Reaction of butadiynyltrialkyltins 1 with cyano(phenyl)iodonium triflates 2 yields 1,3-diynyl(phenyl)iodonium triflates 3, a hitherto unknown class of functionalized diacetylenes. Additionally, the reaction of 3 with triphenylphosphine is described.
