Nature CommunicationsThe one-pot hydrotreatment of phenols to cyclohexyl ethers is crucial but difficult to achieve for fine chemical synthesis owing to the easy overhydrogenation to cyclohexanols over traditional metal–acid bifunctional catalysts.

Synthesis of Solketal Catalyzed by Acid-Modified Pyrolytic Carbon Black from Waste Tires
MoleculesSolketal, a widely used glycerol-derived solvent, can be efficiently synthesized through heterogeneous catalysis, thus avoiding the significant product losses typically encountered with aqueous work-up in homogeneous catalysis.

-Solid Lithium Perchlorate, a Highly Efficient and Chemoselective Catalyst for the Acetalyzation of Aldehydes [PDF]
Journal of Sciences, Islamic Republic of Iran, 2005 -A simple, efficient, and general method has been developed for the chemoselective acetalization of aldehydes with 1,3-propanediol, 1,2-ethanediol and trimethyl orthoformate in the presence of solid lithium perchlorate under solvent-free conditions. Both

Microwave-Assisted Efficient and Chemoselective Acetalization of Aldehydes with Trimethyl Orthoformate [PDF]
Journal of Sciences, Islamic Republic of Iran, 2004 Efficient and chemoselective protection of aldehydes to the corresponding dimethyl acetals have been carried out by mixture of trimethyl orthoformate and methanol in the presence of a catalytic amount of TMSCl or AlCl3 under microwave irradiation.
