Cationic Two-Dimensional Inorganic Network of Antimony Oxide Hydroxide for Lewis Acid Catalysis

Abstract

We have successfully synthesized a rare example of inorganic layered materials possessing the positive charge, which is well outside the isostructural set of layered double hydroxides. The layered architecture consists of two-dimensional corrugated [Sb2O2(OH)]+ layers with linear α,ω-alkanedisulfonate anions residing in the interlamellar space. The cationic material displays a chemical robustness in highly acidic aqueous condition (pH=1). Combining the robust nature and the high density of SbIII sites on the exposed crystal facets, our cationic layered material is an efficient, recyclable catalyst for cyanosilylation of benzaldehyde derivatives with trimethylsilyl cyanide. In addition, the Lewis acidity of the SbIII sites also catalyzes the ketalization of carbonyl groups under “green” solvent-free condition.
