The behavior of iodine pentafluoride towards nucleophilic exchange of fluoride against monofunctional alcoholates in aprotic media is investigated using silylated methanol, isopropanol, tertiary butanol, phenol, alkylated phenol, and pentachlorophenol as educts. 19F-NMR-spectroscopic and preparative details are given for iodine(V)-fluoride- methanolates and fluoride-oxides.

Nano Fe<sub>3</sub>O<sub>4</sub>@ZrO<sub>2</sub>/SO<sub>4</sub><sup>2−</sup>: A highly efficient catalyst for the protection and deprotection of hydroxyl groups using HMDS under solvent-free condition
the protection and deprotection process of various types of alcohols and phenols by HMDS in the presence of nano magnetic sulfated zirconia (Fe3O4@ZrO2/SO42−) as a solid acidcatalyst under very mild and solvent-free condition. This method has interesting advantages like short reaction times and a simple workup process. With regard to some outstanding benefits of this new heterogeneous catalyst such
