Application
Reactant or reagent for:
- Pummerer-like reactions
- Chemoselective deprotection of dimethoxybenzyl ethers
- Mediating oxidative cycloisomerization
- Tosyloxylation of anilides
Used for the direct α-hydroxylation of ketones under acidic conditions. Also employed as a p-fluorination reagent of 4-alkylphenols in the presence of HF·pyridine (cat. no. 184225) for synthesis of 4-fluorocyclohexa-2,5-dienones.
Reagent for the oxidation of N-acylhydrazones to 1,3,4-oxadiazoles. Promotes the cyclization of styryl amines to N-alkyl or N-aryl indoles.

[Structure: see text] A variety of N-arylated and N-alkylated indole derivatives were synthesized by way of a phenyliodine bis(trifluoroacetate) (PIFA)-mediated intramolecular cyclization. This novel method allows for the construction of an indole skeleton by joining the N-atom on the side
