Abstract
Reaction of SF 5Br with various acrylic esters, CH 2CHCOOR, where R = C 2H 5/C(CH 3) 3 and CH 2C(CH 3)COOCH 3, CH 2C(CH 2Cl)-COOC 2H 5, CH 2C( n-C 7H 15)COOC 2H 5 resulted in 1:1 adducts with the SF 5-group attached to the CH 2 portion of the acrylic ester. These adducts were converted to halogen-free saturated esters, an alcohol [SF 5(CH 2) 3OH] an acid [SF 5(CH 2) 2COOH] and a bromide [SF 5(CH 2) 3Br]. Therefore, a method for chain-elongation of SF 5-aliphatic hydrocarbons has been devised. With ethyl acrylate, a 2:1 adduct was also isolated. The reaction of SF 5Cl with (C 2H 5O) 2CCHCOOC 2H 5 gave chloromalonate. The compounds were characterized by their infrared, nuclear magnetic and mass spectral data.
