ABSTRACT The ─N─N─ bond‐containing alkyl hydrazine molecules are widespread in many natural products and biologically active drug molecules. In this context, a developed Ru‐NHC complex 1 , appended with Lewis acidic boron functionality in the secondary coordination sphere, was employed as an efficient catalyst for the selective deoxygenative hydrogenation of tertiary acylhydrazides to alkyl hydrazines using phenylsilane as a reductant under milder reaction conditions. Up to 92% of the selective tertiary alkyl hydrazine was achieved using a minimal silane concentration, without the formation of competitive N─N or C─N bond‐cleaved products.
