Abstract: | In the presence of the ionic liquid bmim]Br/AlCl3 as green reaction medium, methyl 12-benzoyldehydroabietate was synthesized through Friedel-Crafts acylation reactions on
the aromatic ring of methyl dehydroabietate. The optimum synthetic conditions of the target product were found to be as follows:
molar ratio of methyl dehydroabietate to bmim]Br to AlCl3 to benzoyl chloride 1:4:8:8, reaction temperature 40°C, reaction time 2 h. The target product was analyzed and characterized
by means of IR, MS, NMR and elemental analysis. The results show that this novel method has the advantages of mild condition,
short reaction time and environmental benignity.
