71. Synthesis of Multifunctional Aryl(trifloxyalkenyl)iodonium Triflate Salts

Synthesis of Multifunctional Aryl(trifloxyalkenyl)iodonium Triflate Salts, Balázs L. Tóth, Ferenc Béke, Orsolya Egyed, Attila Bényei, András Stirling, Zoltán Novák, ACS Omega 2019, 45, 9188-9197. DOI: 10.1021/acsomega.9b00728 | [Full Text Link] [Supp. Info. Link, CIF]

A convenient procedure for the synthesis of aryl(trifloxyalkenyl)iodonium triflate salts from commercially available (diacetoxyiodo)benzene, trimethylsilyl trifluoromethanesulfonate, and acetylenes under mild conditions was developed. The obtained multifunctional hypervalent vinyliodonium salts equipped with electrophilic and nucleophilic functions could serve as novel C2 synthons for organic transformations. The structure of the iodonium salts was identified by multidimensional NMR spectroscopy and X-ray crystallography.
