双(三氟乙酰氧基)碘苯 - Reference Information
| Use | Used as a multifunctional oxidant; Under acidic conditions, it is used for the direct α-hydroxylation reaction of ketones; In the presence of HF pyridine, it is used as p-fluorinated reagent for 4-alkylphenol, used to synthesize 4-fluorocyclohexane-2, 5-dienone; used for N-acylhydrazone to produce 1,3, 4-Oxadiazole oxidation reaction reagent; used to promote the cyclization reaction of styrylamine to N-alkyl or N-arylindole; dehydrogenation reaction and oxidation reaction reagent; direct conversion of amide to amines (Hoffman Rearrangement) is a new reagent, a key substance for the ordering of carboxyl-terminal peptides; a reagent for desulfurization and acetalization to carbonyl |
| production method | 1.?1.485 grams (5.41 mmol) of iodobenzene dichloride was added to 2.39 grams (10.8 mmol) of potassium trifluoroacetate in a solution of 17 ml of silver. Filtered, the product obtained by lyophilizing the filtrate contains a trace of silver trifluoroacetate. 2. 2g iodobenzene and 4 ml of resteamed trifluoroacetic acid were heated on a water vapor bath for 45 minutes. Pour into ether (50ml), evaporate part of the ether to precipitate yellow and white crystals, and wash with a small amount of ether to wash off the color. 3.20g of diacetic acid iodobenzene is dissolved in 30 ml of hot trifluoroacetic acid to obtain 15g (53%). Bis (trifluoroacetic acid) iodobenzene is crystallized. The first part is dried in a solid sodium hydroxide dryer, which is pure enough. This compound can be recrystallized from acetone-petroleum ether and then cooled to 0 ℃. Another product can be obtained, but it contains diacetate and is seriously impure. In addition, there is a method for electrophilic substitution of tris (difluoroacetic acid) iodine and benzene |
