3'-Chloropropiophenone

3'-Chloropropiophenone is a reagent that is used in the synthesis of maleates. It can be synthesized by reacting hydrochloric acid with 3-chloropropiophenone under conditions where the temperature is kept below 30°C, and the reaction time is limited to five hours. The functional theory behind this reaction involves thionyl chloride as an electrophile that reacts with 3-chloropropiophenone to produce a chloroformate. The chloroformate then reacts with magnesium metal to yield magnesium chloride and 3'-chloropropiophenone. This compound has been shown to have vibrational frequencies of 207, 233, and 240 cm-1. 3'-Chloropropiophenone has also been shown to react with acetonitrile or methylene chloride to form chlorides or isopropyl chloride.
