Hydrolytic kinetic resolution of racemic glycidyl esters on a polymer supported chiral salen cobalt(iii) complex

Agnieszka BUKOWSKA*, Wiktor BUKOWSKI, Sabina KLECZYŃSKA, Katarzyna MATKIEWICZ - Faculty of Chemistry, Rzeszów University of Technology, Rzeszów, Poland Please cite as: CHEMIK 2016, 70, 7, 375–382 The hydrolytic kinetic resolution (HKR) of racemic epoxides occurring in the presence of chiral salen cobalt(III) complex I (Scheme 1) has been discovered accidentally by Jacobsen and coworkers during the studies of the catalytic activity of this complex in the reaction of epoxides with benzoic acid [1]. The presence of a...

Double-side tape based on silicone pressure-sensitive adhesive

Adrian Krzysztof ANTOSIK*, Zbigniew CZECH - Institute of Organic Chemical Technology, West Pomeranian University of Technology in Szczecin, Poland Please cite as: CHEMIK 2016, 70, 7, 369–374 Pressure-sensitive adhesive (PSA) is materials that develop significant adhesive forces upon contact with a substrate without requiring a chemical reaction without leaving residues on the substrate. They can be defined as a viscoelastic material, which in a solvent free state remains permanently tacky at room temperature. To exhibit this property,...
