An imidazolium-cobaltate-based heterogeneous catalyst exhibits advantages over its homogeneous counterpart in the synthesis of β-hydroxyesters from epoxides. However, leaching of cobaltate from the catalytic support decreases the selectivity and recyclability of the catalyst. To overcome such drawbacks, a bis-imidazolium-based covalent triazine framework (CTF) is employed as a catalytic support for the hydroesterification catalyst to reduce cobaltate leaching by the intramolecular anion stabilization effect of the multi-imidazolium moiety, resulting in an excellent selectivity for the β-hydroxyester and unprecedented recyclability.

A low-valent titanium species derived in situ from Ti(O-i-Pr)4, Me3SiCl and Mg powder in tetrahydrofuran reacted with epoxides to selectively provide less hindered alcohols via a homolytic ring-opening of epoxides, in which the intermediate β-titanoxy radical intramolecularly abstracted a hydrogen atom from an alkoxy moiety in the titanium complexes.
Hexafluoroisopropanol: A powerful solvent for the hydrogenation of functionalized aromatic compounds
Fache, Fabienne,Piva, Olivier

Various substituted aromatic compounds have been reduced under H 2 using RuCl3. The fluorous solvent hexafluoroisopropanol turned out to be particularly efficient in the case of compounds difficult to reduce in organic solvents.
