1- (2,4,6-trifluorobenzyl) -1H-pyrazole-2,5-dimethanol is an organic compound. This substance has the following chemical properties:
- ** Acidic and basic **: The nitrogen atom in the 1H-pyrazole ring contains lone pairs of electrons, which can be used as Lewis base. It interacts with proton or electron-deficient species and exhibits alkalinity. However, the hydrogen atom attached to nitrogen on the pyrazole ring can be dissociated under certain conditions and presents a weak acidity. The overall acidity and alkalinity of the compound is significantly affected by its chemical environment. < Br > - ** Nucleophilic Substitution Reaction **: The hydroxyl group of the 2,5-dimethanol part is a nucleophilic check point. When encountering electrophilic reagents, nucleophilic substitution reactions are prone to occur. For example, when reacting with halogenated hydrocarbons, the lone pair electrons of the hydroxyl oxygen atom attack the carbon atom of the halogenated hydrocarbon, and the halogen ions leave to form ether compounds.
- ** Oxidation Reaction **: Hydroxyl groups can be oxidized. Under the action of appropriate oxidizing agents, such as mild oxidizing agents (such as Dess-Martin oxidizing agents), it can be oxidized to aldehyde groups; if stronger oxidizing agents (such as potassium permanganate) are used, it may be further oxidized to carboxyl groups. < Br > - ** Esterification Reaction **: Hydroxy groups can be esterified with carboxylic acids or their derivatives (such as acyl chloride, acid anhydride). Under acid catalysis or base catalysis, hydroxy groups dehydrate and condensate with carboxylic groups to form ester bonds and form corresponding ester compounds.
- ** Ring Related Reactions **: The 1H-pyrazole ring has certain aromatic properties and stability, and can participate in a variety of ring reactions. If under suitable catalysts and reaction conditions, electrophilic substitution reactions can occur, and other functional groups can be introduced into the pyrazole ring. The fluorine atom of the 2,4,6-trifluorobenzyl part has strong electron-absorbing properties, which can affect the electron cloud density of the pyrazole ring and have an effect on the activity and selectivity of the ring reaction.
