Abstract:	Addition of pentafluorothio bromide, SF₅Br, to ethyl propiolate results in an 1:1 adduct, SF₅CHCBrC(O)OC₂H₅, and a small amount of a 1:2 adduct. The former is converted by reduction to the corresponding β-SF₅-acrylic ester, SF₅CHCHC(O)OC₂H₅. Treatment of SF₅CH₂CBr(CH₃)C(O)OCH₃ with base produces methyl-β-SF₅-methacrylate, SF₅CHC(CH₃)C(O)OCH₃. The preparation and characterization of these new compounds are described.

Keywords:	β-SF₅-acrylates Pentafluorothio (SF₅) Sulfur hexafluoride derivatives
