Pentanoyl chloride is an acyl chloride derived from pentanoic acid. It is a colorless liquid that is used to attach the valeroyl group. It is usually produced by chlorination of valeric acid.[1]
Like related acyl chlorides, valeryl chloride hydrolyzes readily:
CH3(CH2)3C(O)Cl + H2O → CH3(CH2)3CO2H + HClAlcohols react to give esters:
CH3(CH2)3C(O)Cl + ROH → CH3(CH2)3CO2R + HClAmines react to give amides:
CH3(CH2)3C(O)Cl + R2NH → CH3(CH2)3C(O)NR2 + HClBenzene reacts under conditions of the Friedel-Crafts reaction to give valerophenone:
CH3(CH2)3C(O)Cl + C6H6 → CH3(CH2)3C(O)C6H5 + HCl
