Go organic! N‐Heterocyclic carbene (NHC) 1,3‐diisopropyl‐4,5‐dimethylimidazol‐2‐ylidene (IiPr) has been found to be an efficient and selective catalyst for the dehydrogenativecoupling 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
