Phenol compound ortho-position direct fluorination method
-
Paragraph 0049-0051, (2020/04/17)
The invention relates to a phenol compound ortho-position direct fluorination method which comprises the following steps: reacting a phenol compound shown in a formula (1A) with a fluorination reagentin a solvent under the action of a photocatalyst and a light source at room temperature, and separating and purifying a reaction mixture after the reaction to obtain a fluorinated phenol compound shown in a formula (2A). The advantages are as follows: the method for directly fluorinating phenol by organic photocatalysis is simple in operation process; raw materials are commercialized and easy toobtain; the photocatalyst is low in price, easy to obtain and environmentally friendly; the reaction condition is mild; the site selectivity is high; the reaction is efficient; and a fluorinated phenol derivative can be prepared only through one step.

DIRECT FLUORINATION OF PHENOL AND CRESOLS

, p. 159 - 172 (2007/10/02)
A study has been made of the reaction of phenol with elemental fluorine using a variety of solvents and reaction temperatures.Yields of o- and p-fluorophenol were obtained as high as 85percent.The isomer ratio changed drastically between phenol conversions of 10percent and 56percent.The o-isomer changed to unidentified polymeric substances at higher conversion, but it might also be assumed that interconversion of some isomers is occuring.The three cresols have also been succesfully fluorinated with elemental fluorine. p-Cresol gave some expected 2-fluoroderivative but also formed a fluorocyclohexadienyl ketone.
