Cyanocalix[4]arenes: Synthesis, crystal structures and reactivity studies
Applewhite, Malcolm J.,Haynes, Delia A.,Arnott, Gareth E.
, p. 475 - 484 (2016)
Herein, we describe an improved method to synthesise mono-, di- and tetra-cyanocalix[4]arene and report their crystal structure determinations. We also report our attempts to further functionalise the cyanocalix[4]arenes into dithiadiazolyl-calix[4]arenes
Mixed metal MgO-ZrO2 nanoparticle-catalyzed O-tert-Boc protection of alcohols and phenols under solvent-free conditions
Gawande, Manoj B.,Shelke, Sharad N.,Branco, Paula S.,Rathi, Anuj,Pandey, Rajesh K.
experimental part, p. 395 - 400 (2012/09/25)
An environmentally benign method for O-tert-Boc protection of alcohols and phenols catalyzed by MgO-ZrO2 nanoparticles under solvent-free conditions is described. A variety of phenols, alcohols (aliphatic and aromatic) were converted to corresponding O-tert-Boc products in good to excellent yield (50-95%). The present protocol is expedient, simple, and efficient under solvent-free conditions. The MgO-ZrO2 Nps are easily prepared from inexpensive precursors, and are reusable, recyclable and chemoselective. Copyright 2012 John Wiley & Sons, Ltd. Copyright
