Hierarchical Beta zeolite was prepared using piperidine based structure directing agents having at least two ammonium groups in their structure. Materials exhibited very high surface area (≈1050 m2 g -1), pore volume (2.7 mL g-1), and catalytic activity hitherto reported in the literature. A density functional theoretical study shows that a suitable special orientation of piperidine rings in the structure directing agents is responsible for the formation of hierarchical Beta.

In the presence of small amounts of ferric chloride substituted 9-benzoylanthracenes are deacylated, isomerized, and reacylated.The degree of transformation of the ketones increases with increase in the effective volume of the substituent at the ortho position to the acyl and with increase in the electron-donating characteristics of the substituent in the aromatic rings.
