The potassium fluoroborates K[RCF=CFBF 3 ] (R = F, Cl ( cis ‐/ trans ‐mixture), trans ‐C 4 F 9 , cis ‐C 2 F 5 , cis ‐C 6 F 13 , trans ‐C 4 H 9 , trans ‐C 6 H 5 ) were prepared by fluoridation (methoxide‐fluoride substitution with K[HF 2 ]) of RCF=CFB(OMe) 2 and Li[RCF=CFB(OMe) 3 ] which were obtained from RCF=CFLi and B(OMe) 3 . The K[RCF=CFBF 3 ] salts were characterized by their 1 H, 11 B, 19 F NMR and IR spectra.
