Geo‐inspired activation: The first example of silanediolsactivating amide and aldehyde substrates through hydrogenbonding is described. Both NMR and X‐ray co‐crystallization studies demonstrate binding modes and affinity, and show that silanediolhydrogen‐bonding assemblies can be modulated by the addition of carbonylcompounds. These silanols show catalysis in a Diels–Alder reaction and provide
