A robust alcohol amination protocol using common saturated cyclic amines and primary alcohols as starting material is described for synthesis of 29 compounds. The reactions are catalyzed by combination of dichloro(p ‐cymene)ruthenium(II) dimer precatalyst with triphenylphosphine ligand. The catalyst can be precipitated by addition of hexane or cold diethyl ether, followed by isolation of the product

We report a competent and selective hydrosilylation of nitriles and tertiary amides catalyzed by the readily available zinc bis(hexamethyldisilazide) under solvent-free and mild conditions, making it a sustainable and desirable alternative to existing methods. Both protocols afforded high conversion, superior selectivity, and a broad substrate scope, from electron-withdrawing to electron-donating and
