The multi‐step reaction cascade involves amine‐to‐enamine dehydrogenation at two alkyl residues and two electrophilic silylation reactions of those enamines, one inter‐ and one intramolecular.en540 Chemie und zugeordnete WissenschaftenaminesboronC−H activationSi−H activationsiliconConsecutive β,β′‐Selective C(sp3)−H Silylation of Tertiary Amines with Dihydrosilanes Catalyzed by B(C6F5)3Article2021-06-141521-3757
