In this article, a selective formal anti-Markovnikov hydroamination of allyl alcohols is presented. It enables the versatile synthesis of valuable γ-amino alcohol buildingblocks. A phosphine-free Earth’s abundant manganese(I) complex catalyzed the reaction under hydrogen-borrowing conditions. A vast range of aliphatic, aromatic amines, drug molecules, and naturalproduct derivatives underwent successful

Abstract A one-pot, simple, selective, and efficient protocol for the synthesis of aromatic secondary amines from various nitro arenes and nitriles in the presence of 10% Pd/C catalyst under H2 at atmosphericpressure and ambient temperature in tetrahydrofuran is illustrated. The scope and limitations of this method have been examined.

nonpolar solvent, features exclusive anti-Markovnikov selectivity, broad substrate scope (>70 examples), and good functional group tolerance. The reaction could be performed at gram scale and applied to the synthesis of drug molecules and heterocyclic compounds. When chiral substrates are used, the stereochemistry and enantiomeric excess are retained. Further application of the chemistry is seen in the
