Structure‐reactivity study of a family of electrophilic monofluoromethylating reagents based on sulfonium ylide skeleton with different steric hindrance and electron‐withdrawing properties was described. These studies led us to discover two highly reactive reagents 3 with a cyclic malonate backbone and 6 with an electron‐poor 1,1,1,5,5,5‐hexafluoropentane‐2,4‐dione backbone. The high reactivity of reagent
