Channel zapping : PKU‐1 and newly synthesized PKU‐2 (Al 2 B 5 O 9 (OH) 3 ⋅ n H 2 O; see picture) possess microporous structures with 18‐ring and 24‐ring channels, respectively. They show high reactivity and size selectivity in the cyanosilylation of aldehydes as heterogeneous Lewis acid catalysts. The different channel sizes determine the substrate selectivity. These examples demonstrate the potential of octahedron‐based aluminoborate channels in catalysis.
