A Lewis acid catalytic core sandwiched by inorganic polyoxoanion caps: selective H2O2-based oxidations with [Al(III)4(H2O)10(β-XW9O33H)2](6-) (X = As(III), Sb(III))

Abstract

The Al(III)-containing polyanions [Al(III)4(H2O)10(β-XW9O33H)2](4-) with X = As(III) (1) and Sb(III) (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.
