We report herein a pincer Ru-catalyzed dual intramolecular dehydrogenative silylation of primary C(sp³)–H bonds. The reaction features high efficiency, scalability, and good functional group tolerance, allowing a facile and atom-economical access to structurally diverse silicon-centered spirocycles, including unprecedented oxa-spirosilabiindanes and aza-spirosilabiindanes.
