Valerophenone, or butyl phenyl ketone, is an aromatic ketone with the formula C6H5C(O)C4H9. It is a colorless liquid that is soluble in organic solvents. It is usually prepared by the acylation of benzene using valeryl chloride.[1]
Selected reactions
[edit]Being prochiral, valerophenone undergoes enantioselective hydrogenation to the corresponding alcohol.[2]
Its photochemistry has been studied.[3][4]
Valerophenone is also an inhibitor of the enzyme carbonyl reductase.[5]
