Direct access to amines from biomass‐based phenols via deoxygenative transformation remains greatly challenging in organic synthesis. Herein, we present a palladium‐catalyzed deoxygenative amination of phenols (and their benzyl ether) with hydrazine as nitrogen source. The hydroxylamine/formic acid can be substituted for hydrazine in some cases. This deoxyamination features the involvement of a complex
