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.

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.

Wang, Jian-Ping published the artcileTwo Strandberg-type organophosphomolybdates: synthesis, crystal structures and catalytic properties, Related Products of dioxole, the publication is Dalton Transactions (2014), 43(45), 17172-17176, database is CAplus and MEDLINE.

Two novel Strandberg-type organophosphomolybdate hybrid compounds [(Cu(H₂O))₂(μ-bipy)₂(C₆H₅PO₃)₂Mo₅O₁₅]_n (1) and [(Cu(H₂O)₂)₂(μ-bipy)(C₆H₅PO₃)₂Mo₅O₁₅]_n (2) (bipy = 4,4′-bipyridyl) were prepared under mild hydrothermal conditions and structurally characterized by physicochem. and spectroscopic methods. Single crystal x-ray diffraction anal. reveals that compounds 1 and 2 are polyoxometalate-based Cu-coordination polymers with a three-dimensional framework. In 1, the Cu²⁺ ions not only link [(C₆H₅PO₃)₂Mo₅O₁₅]^4- (abbreviated as {(C₆H₅P)₂Mo₅}) polyanions, but also act as connectors of bipy ligands to produce two sym. 1-dimensional chains, and all 1-dimensional chains are further held together by polyanions to generate a 3-dimensional network. In 2, each {(C₆H₅P)₂Mo₅} polyanion acting as a hexadentate ligand links four Cu(II)-bipy/H₂O units, forming 2-dimensional plane structures, which are further bridged by Cu(II)-bipy-Cu(II) fragments to generate a 3-dimensional network. Their fluorescence properties and catalytic properties for the synthesis of cyclohexanone ethylene ketal were also studied.

Gundekari, Sreedhar published the artcileSelective preparation of renewable ketals from biomass-based carbonyl compounds with polyols using β-zeolite catalyst, Quality Control of 177-10-6, the publication is Molecular Catalysis (2022), 112269, database is CAplus.

The preparation of ketals from biomass-based carbonyl compounds and polyols was demonstrated. The emphasis is on levulinate-based ketals using Et levulinate (EL) with ethylene glycol (EG) or glycerol (Gly) as polyols. Among the catalysts screened, Na-β zeolite resulted in 99% conversion of EL with 100% selectivity for the corresponding ketal within 1 h, when used in conjunction with azeotropic distillation in cyclohexane medium. Using Gly as the polyol, a similar yield and selectivity was obtained, albeit after a longer reaction time (4 h). The authors explored the reaction scope by using a multitude of biomass-based ketones and polyols as reactants, which showed excellent selectivity for the ketals. Slight deactivation of the catalyst was observed after reaction, owing to the deposition of organic carbon on the catalyst, which was identified using anal. tools. The deactivated catalyst was regenerated on calcination. This strategy was successfully demonstrated for ketal preparation using crude glycerol with EL.

Acetalized [60]fullerenes were synthesized from cyclohexanone-fused [60]fullerene, which was facilely prepared by Diels-Alder reaction of C₆₀ with 2-trimethylsilyloxy-1,3-butadiene, on treatment of various aliphatic alcs. under TiCl₄ catalyst. The spiro-cyclic acetalized [60]fullerenes having five, six, and seven-membered rings were also synthesized by using the corresponding diols under the same condition. The slightly raised reduction potentials E^red (∼0.04 V) relative to those of PCBM were observed by cyclic voltammetry measurement, depending on the identity of alkyl group/chain. The noncyclic acetalized [60]fullerenes showed lower thermal stability up to 200°, while the cyclic ones exhibited the drastically improved thermal stability up to 350° under nitrogen atm. The acid-catalyzed hydrolysis easily removed the acetal moiety quant., resulting in a considerable change of solvent solubility of the fullerene.
