Go organic! N‐Heterocyclic carbene (NHC) 1,3‐diisopropyl‐4,5‐dimethylimidazol‐2‐ylidene (I i Pr) has been found to be an efficient and selective catalyst for the dehydrogenative coupling of a wide range of silanes and hydroxyl groups to form SiO bonds under mild and solvent‐free conditions (see scheme). Mechanistic studies indicated that the activation of hydroxyl groups by the NHC is the most plausible initial step for the process.
