The heterogeneous catalyst Sn-β is currently prepared in a complicated hydrothermal synthesis, which has several hurdles that prevent its industrial implementation. In their Communication on page 11736 ff., I. Hermans and co-workers report a convenient preparation of Sn-β by solid-state ion exchange. It requires much less time and synthetic skill, and the product has more favorable catalytic properties, giving space–time yields over one order of magnitude higher than previously observed.
