(Phenyl)[3-(Trimethylsilyl)-2-naphthyl]iodonium Triflate as a New Precursor of 2,3-Didehydronaphthalene

1,3-Dipolar cycloaddition of sugar azides with benzyne: a novel synthesis of 1,2,3-benzotriazolyl glycoconjugates

“…1 H NMR spectra were recorded at 300 MHz with TMS as the internal reference. 13 C NMR spectra are recorded at 75 MHz with CDCl 3 as the internal reference. Chemical shifts are given in parts per million downfield from internal standard Me 4 Si and coupling constants are given in Hertz.…”

“…The alternative method for the synthesis of benzotriazole is the cycloaddition of azides with arynes. [13][14][15] In recent years, benzyne was generated in situ from 2-(trimethylsilyl)phenyl trifluoromethanesulfonate using cesium fluoride under mild conditions and used in various cycloaddition reactions. [16][17][18][19][20][21] Since benzotriazole-linked glycoconjugates have become increasingly useful and important in glycobiology, 22-25 the development of a simple, convenient, and efficient method for their synthesis in a single-step operation is desirable.…”

Strategies in Organic Synthesis for Condensed Arenes, Coronene, and Graphene

“…For example, Kitamura et al reported a new hypervalent iodide precursor 27 for the in situ generation of naphthyne, which can be trapped in a Diels-Alder reaction to form PAHs, such as 28 and 29 (Scheme 8) [29]. A.-F. Tran- Van and H.A.…”

Diaryliodoniumsalze – aus dem Nichts ins Rampenlicht

“…[173] Verschiedene andere Diaryliodoniumsalze, einschließlich heteroaromatischer Vertreter, wurden ebenfalls als Benzin-Vorstufen eingesetzt. [174] 3.5.3. Makromolekulare Chemie Stang und Mitarbeiter führten zahlreiche Studien zur Anwendung von Diaryliodoniumsalzen in der makrocyclischen Chemie durch.…”
