Reactions
editLike related acyl chlorides, valeryl chloride hydrolyzes readily:
- CH3(CH2)3C(O)Cl + H2O → CH3(CH2)3CO2H + HCl
Alcohols react to give esters:
- CH3(CH2)3C(O)Cl + ROH → CH3(CH2)3CO2R + HCl
Amines react to give amides:
- CH3(CH2)3C(O)Cl + R2NH → CH3(CH2)3C(O)NR2 + HCl
Benzene reacts under conditions of the Friedel-Crafts reaction to give valerophenone:
- CH3(CH2)3C(O)Cl + C6H6 → CH3(CH2)3C(O)C6H5 + HCl
