Abstract
Variable-temperature 2H NMR reveals that the THF ligands are highly labile in Ln(BH4)2(THF)2/HY30, undergoing exchange between Ln sites under confinement via low-coordinate intermediates. Potency in catalytic C–H borylation likely emerges from access to highly electrophilic, electronically unsaturated species.
