Preliminary NoteAddition of 1,2-Dibromotetrafluoroethane (cas 124-73-2) to alkynes by means of a redox system

Add time:09/27/2019    Source:sciencedirect.com

The addition of 1,2-Dibromotetrafluoroethane (cas 124-73-2) (1) to various terminal alkynes (2a – 2j) was performed in DMF with a redox system (NH4)2S2O8/HCO2Na·2H2O at 40°C. The products (3) were 1:1 adducts reductively debrominated under the reaction conditions, with the E isomers in predominance, and were obtained in excellent yields (82 – 93%).
