Lanthanum Catalyzes CH Borylation Inside Zeolite Micropores

The zeolite-supported lanthanum borohydride, La(BH4)x-HY30, catalyzes C–H borylation of benzene with pinacolborane (HBpin) at 120 °C to give PhBpin. By capping the external silanol on zeolite particles, the single-site La catalyst was selectively grafted at Brønsted acid sites in micropores, increasing turnovers compared to La grafted on the unprotected support.
