Reakcijska shema:

Sinteza:
1. V erlenmajerico dodamo 1000 g 4-metilpropiofenona.
2. Vlijemo 6000 ml acetonitrila ali etilacetata in začnemo mešati.
3. Med mešanjem počasi dodajamo bakrov(II) bromid 1800 g.
4. Na bučko namestimo povratni hladilnik.
5. Pod povratnim tokom segrevamo 24 ur.
6. Po tem času prenehajte segrevati in mešati.
7. Po potrebi destiliramo topilo, da dobimo suh bromoketon.
8. Etil acetat pustimo stran, če nameravamo v njem reagirati. Teoretični izkoristek: 1400 g.

Z uporabo etilacetata je ta večinoma končan v eni uri. Dokončano v 2 urah.

Ali lahko to metodo uporabimo z valerofenonom, da dobimo a-bromovalerofenon?
