ChemInform Abstract: A Lewis Acid Catalytic Core Sandwiched by Inorganic Polyoxoanion Caps: Selective H2O2‐Based Oxidations with [AlIII4(H2O)10 (β‐XW9O33H)2]6‐(X: AsIII, SbIII).

Abstract

The AlIII-containing polyanions [AlIII4(H2O)10(β-XW9O33H)2]4− with X = AsIII (1) and SbIII (2) feature four aluminum(III) centers sandwiched by two trivacant (β-XW9O33) Keggin units, and trigger peroxide catalysis as well as substrate coordination via multiple Lewis acid site interactions.
