Abstract: Twenty acid chlorides, 4-(mono/di-benzyloxy)-4-ketobutanoyl chlorides (Ia–XXa) were synthesised by the reaction of monoesters of succinic acid with thionyl chloride. The product thus obtained (4-benzyloxy-4-ketobutanoyl chlorides) was treated with diethylcadmium to convert it into the corresponding keto-esters (Ib–XXb), the mono/di-benzyl-γ-ketohexanoates, with a good yield. All the compounds thus prepared were characterised by physical, spectroscopic (UV-VIS, IR, 1H NMR, 13C NMR), and mass measurements techniques.

Keywords: γ-ketoesters – mono/disubstituted-benzyl alcohols – diethylcadmium – monoesters of succinic acid
