2012_32b/2012Back Cover Picture: Strong Organic Bases as Building Blocks of Mesoporous Hybrid Catalysts for C–C Forming Bond Reactions (Eur. J. Inorg. Chem. 32/2012)

The back cover picture shows 1,8-bis(tetramethylguanidino)naphthalene (TMGN) as a neutral organic base that combines the properties of guanidine and the properties of proton sponges. TMGN was used as building block to obtain organic–inorganic silica-based mesoporous hybrids with strong basic properties. By means of a NH4F-catalyzed sol–gel process, the use of surfactants was avoided. The organic base was preserved inside the mesoporous silica network, providing strong basic properties to the hybrid materials. The hybrid materials have shown high conversions and recyclability in Knoevenagel condensations of different methylene compounds and in Henry and Claisen–Schmidt reactions. Details are discussed in the article by A. Corma et al. on p. 5175 ff.
