Alcohol CF*3*-reagent, more commonly termed Togni reagent I, is the first hypervalent iodine-CF*3* reagent that was commercialized. From the both Togni reagents, this reagent is clearly much better soluble in organic solvents (even in pentane). The reagent contains a relatively basic alkoxide group, meaning that formal oxidative insertion on a metal centre creates a new higher valent CF*3*-metal complex containing 2-(2-iodophenyl)-propanolate as a ligand. Such inherent basicity can be helpful for design of catalytic trifluoromethylation processes in which deprotonation generates the active nucleophile.
