𝛽-Dicarbonyl compounds; ferric hydrogen sulphate Fe(HSO₄)₃; 𝐶-alkylation; heterogeneous catalyst.

Fe(HSO₄)₃(FHS) was used as an efficient catalyst for the heterogeneous addition of a series of benzylic and allylic alcohols to various 𝛽-dicarbonyl compounds, which afforded moderate to excellent yields of 𝐶-alkylated products in 1,2-dichloroethane. In comparison with the previous methods, the present research surprisingly exhibited higher reaction yields without formation of any by-products which could be formed by self-condensation of alcohols. Moreover, the catalyst can be readily recovered and reused up to five times with almost maintained reactivity and yields.
