Liu, Xiaoxia published the artcileA simple approach to the preparation of H₆P₂W₁₈O₆₂/Cu₃(BTC)₂ (BTC = 1,3,5-benzenetricarboxylate) and its catalytic performance in the synthesis of acetals/ketals, Category: dioxole, the publication is Reaction Kinetics, Mechanisms and Catalysis (2015), 116(1), 159-171, database is CAplus.

H₆P₂W₁₈O₆₂/Cu₃(BTC)₂ (BTC = 1,3,5-benzenetricarboxylate) as a new catalyst was prepared by the impregnation method and used to synthesize cyclohexanone ethylene ketal as a probe reaction, which has shown its favorable catalytic activity. FT-IR, XRD, SEM, N₂ adsorption-desorption isotherms and TG/DTA were used to characterize its composition, structure, morphol., stability and toleration for thermal in order to further prepare the catalyst with effective performance. Moreover, we have also explored the optimized conditions of carrying out the probe reaction by orthogonal experiments The optimized conditions were as follows: fixing cyclohexanone consumption was 0.02 mol, n(cyclohexanone):n(ethylene glycol) = 1:1.3, the mass ratio of the catalyst to total reactant was 0.2 %, cyclohexane dosage was 4 mL, and the reaction time was 75 min. The yield of the acetals and ketones could reach 54.9 ∼ 83.5 % under the optimum conditions. In addition, H₆P₂W₁₈O₆₂/Cu₃(BTC)₂ exhibited good reusability and the approaches above may enable rational design of advanced and environmental-friendly MOF-based catalysts.

Yang, Liu published the artcileSynthesis of cyclohexanone ethylene ketal catalyzed by Keggin type biimidazole tungstogermanate, Formula: C8H14O2, the publication is Yingyong Huaxue (2014), 31(11), 1310-1316, database is CAplus.

A Keggin-type biimidazole tungstogermanate (H₄biim) [H₂GeW₁₂O₄₀]·18H₂O (1b, H₂biim = 2,2′-biimidazole), as a catalyst for the synthesis of cyclohexanone ethylene ketal, was designed and synthesized. It was characterized by single crystal X-ray diffraction anal., IR spectroscopy (FT-IR), UV spectroscopy (UV), thermogravimetry-DTA (TG-DTA) and X-ray powder diffraction (XRD). Factors, such as the molar ratio of cyclohexanone to ethylene glycol, catalyst loading and reaction time, on the yield were investigated. The exptl. results show that the product yield reaches 90% under the optimal conditions: n(cyclohexanone):n(1,2-ethanediol) = 1:1.4, n(1b, based on W): n(cyclohexanone) = 1:260, and reaction time 2 h. The catalyst can be reused and has good stability in the catalytic reaction.

Bonilla-Landa, Israel published the artcileHafnium(IV) Chloride Catalyzes Highly Efficient Acetalization of Carbonyl Compounds, Category: dioxole, the publication is Current Organic Synthesis (2019), 16(6), 913-920, database is CAplus and MEDLINE.

Hafnium(IV) tetrachloride efficiently catalyzes the protection of a variety of aldehydes and ketones RC(O)R¹ (R = Ph, 4-butylphenyl, pyridin-2-yl, octyl, etc.; R¹ = H, Me, Et), including benzophenone, acetophenone, and cyclohexanone, to the corresponding di-Me acetals and 1,3-dioxolanes, RC(OR²)₂R¹ (R² = Me, -(CH₂)₂-) under microwave heating. Substrates possessing acid-labile protecting groups (TBDPS and Boc) chemoselectively generated the corresponding acetal/ketal in excellent yields.
