- ItemNMR studies and crystal structure determinations of CF3 group-containing bieyelie phenolates(Berlin : de Gruyter, 2009) Mamat, C.; Reinke, H.; Langer, P.Three new CF3-substituted bicyclic salicylate derivatives were synthesized by the TiCl4-mediated cyclization of trifluoromethyl- containing ketones with l,3-bis(silyl enol ethers) and characterized by NMR and IR, spectroscopy, mass spectrometry and elemental analysis. The crystal structures of the bicyclic derivatives have been determined by single crystal X-ray analysis. All structures exhibit hydrogen bonding. © 2009 Verlag der Zeitschrift für Naturforschung.
- ItemAn 8-fold parallel reactor system for combinatorial catalysis research(New York : Hindawi, 2006) Stoll, N.; Allwardt, A.; Dingerdissen, U.; Thurow, K.Increasing economic globalization and mounting time and cost pressure on the development of new raw materials for the chemical industry as well as materials and environmental engineering constantly raise the demands on technologies to be used. Parallelization, miniaturization, and automation are the main concepts involved in increasing the rate of chemical and biological experimentation. Copyright © 2006 Norbert Stoll et al.
