Ketone di-sec-alkyl acetals are obtained in good to excellent yields by treatment of ketones with tri-sec-alkyl orthoformate and the corresponding alcohol in the presence of a catalytic amount of cerium(III) trifluoromethanesulfonate. Georg Thieme Verlag
Process for the preparation of ketals

, (2008/06/13)
Ketals of longer-chain or branched alcohols are prepared from dimethyl ketals or their ketones by reaction of the dimethyl ketals and the alcohols at high temperatures of 150° to 180° C. in the presence of acid catalysts. The enol ethers and mixed ketals which are separated by distillation are added to the next reaction batch and also react to form the target product. The starting material, dimethyl ketal, may also be formed during the reaction from the ketone and trimethyl orthoformate.
