Synthesis and characterization of (pentafluorosulfur)acetylenes

New acrylate systems: derivatives of β-SF5-acrylic acid

“…It has been shown that SF 5 X (X ¼ Cl, Br) will add to alkynes; SF 5 Cl was added to acetylene and propyne [5] and to RCBCOR 0 (R¼CH 3 , H; R 0 ¼CH 3 , CH 3 CH 2 ) [6,7] while in separate reports, SF 5 Br was added to YCBCH (Y ¼ SF 5 , CF 3 ) and to CF 3 CBCH or CH 3 CBCH [8,9]. In all cases, the SF 5 group was attached to the olefinic carbon with the most hydrogen.…”

Cooperative excited-state behavior in platinum(II) Magnus-type double-salt materials. Active and inactive photosensitizers for hydrogen production in aqueous suspension

“…One compound of particular interest is ethynylsulfur pentafluoride (SF5C=CH) which has been used as the starting reagent for a number of novel and interesting derivatives that include saturated ethers, vinyl ethers, pyrazoles, cyclic alkenes, and alkyl-substituted phenylsulfur pentafluorides.2 3In addition, SF5C=CH is found to be useful in preparing a number of SF5-containing alkenes and alkynes. 2,3 Results and Discussion…”

Preparation and Utility of Organic Pentafluorosulfanyl-Containing Compounds

“…1:1 ratio) of the product of the latter reaction was confirmed by GC and NMR analyses. Intriguingly, a 1979 study on addition of SF 5 Br to 146d reports a 75% yield of adduct after just 3 h at 105 °C …”
