To test the stability and recyclability of 1templated and 1-nontemplated, we performed cycling studies under the same catalytic conditions. After 3 h, the materials were washed with acetone and re-subjected to the reaction conditions (see SI). Both catalysts remain stable over five cycles, showing little variation in yields (Fig. ), no loss in crystallinity (Fig. ), and no change in functional group composition (Figs. and).
