4-acetylphenyl trifluoromethanesulfonate

Description:
4-Acetylphenyl trifluoromethanesulfonate, also known as 4-acetylphenyl triflate, is an organic compound characterized by the presence of an acetyl group attached to a phenyl ring, which is further substituted with a trifluoromethanesulfonate group. This compound is typically a colorless to pale yellow liquid and is known for its high reactivity, particularly in electrophilic aromatic substitution reactions. The triflate group is a potent leaving group, making this compound useful in various synthetic applications, including the formation of carbon-carbon bonds and the introduction of functional groups in organic synthesis. It is soluble in organic solvents such as dichloromethane and acetonitrile, but its solubility in water is limited. Due to the presence of the trifluoromethanesulfonate moiety, it exhibits strong electron-withdrawing properties, which can influence the reactivity of the aromatic ring. Safety precautions should be taken when handling this compound, as it may be harmful if inhaled or ingested, and appropriate protective equipment should be used.
