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

Synthesis and reactions of 2-SF5-butadiene

“…The values for these compounds are in excellent agreement with SF 5 -carbon compounds [14]. Some of our early cycloaddition studies centered around the use of SF 5 -acrylic esters [15]. In one study, an adduct in low yields (32%) was obtained with an SF 5 -acrylic ester (see below).…”

A convenient and efficient method for incorporation of pentafluorosulfanyl (SF5) substituents into aliphatic compounds

“…More versatile in its additions to alkynes, SF 5 Br was earlier found to add effectively to propyne, 3,3,3-trifluoropropyne, propargylic esters and acetylene itself [30][31][32]. Under our low temperature, Et 3 B-initiated conditions it gave excellent yields of adducts with terminal and internal, alkyl or aryl substituted alkynes.…”

Synthesis of new pentafluorosulfanylacrylates (F5SCHCHCHO, F5SCHCHCN, F5SCHCHCOOCH3) and use of them as dienophiles in Diels-Alder reaction

“…Though a great many number of fluorinated acrylates are known only a limited number containing the SF 5 -group have been reported. The first SF 5 -containing acrylates and its polymers in which the SF 5 is present in the acid moiety were synthesized at the end of 90 years [1][2][3][4].…”

“…At the same time, the methods for the synthesis of acrylates with pentafluorosulfanyl group in unsaturated moiety are still limited. Only in 2004, did Gard and coworkers report the preparation of esters of b-SF 5 -acrylic and methacrylic acids [5]. More recently, in our laboratories, we have used new approach for synthesis of SF 5 -containing unsaturated compounds and for the first time were synthesized the F 5 SCH CHCOR (R OH, CH 3 ) [6].…”
