N-Heterocyclic olefins (NHOs) are promising organocatalysts with strong nucleophilicity and Brønsted basicity. NHOs are efficient promoters for a direct dehydrogenative silylation of alcohols or hydrosilylation of carbonyl compounds. Preliminary results of an asymmetric dehydrogenative silylation are also discussed.
