Undecan-x-ones (x = 2 – 6) have been used as starting materials in the synthesis of ethylene and propylene acetals, undecan-x-ols and their acetates. Acetals were prepared in the reaction between ketones and ethane-1,2-diol or propane-1,2-diol in toluene in the presence of sulfosalicylic acid as a catalyst. Alcohols were synthesised in the reduction of ketones with sodium borohydride in water/propan-2-ol. Acetates were prepared by esterification of alcohols with acetic anhydride in the presence of sodium acetate. All derivatives were prepared in a 2 – 5 g scale.
Ethylene acetal of undecan-3-one and all propylene acetals are newly prepared compounds. Physical properties (boiling point, refractive index) and spectral data (IR, ¹H NMR) for all the synthesized derivatives of undecan-x-ones have been determined.
