Abstract
Two new organobridged silica-based materials have been prepared by sol–gel hydrolysis-condensation of ureido silyl derivatives of an enantiopure chiral trans 1,2-diaminocyclobutane and an achiral meso 1,2-diaminocyclobutane. The influence of the relative and absolute configuration of the stereogenic centers on the morphology and characterization parameters of the resulting materials has been studied. A right-handed helical shape has been observed for the material obtained starting from the meso-cis diamine whereas the material obtained from the chiral trans diamine showed aggregation in the form of platelets. A preliminary experiment of a reduction of a ketone by hydride transfer reaction catalyzed by a rhodium complex embedded in an organic–inorganic hybrid silica is also reported.
