one ain't bad: Various tertiary, secondary, and primary amines are synthesized in moderate to quantitative yield by the hydrogenation of nitriles under flow conditions. This method enables selective synthesis of three different types of amine from one type of nitrile by using commercial Pd/C or Rh/C catalysts and solvents. The catalyst-packed cartridge is continuously used for at least 72 h.
The first report of a Bronsted acidic ionic liquid, 1-methylimidazolium tetrafluoroborate [(HMIm)BF(4)], catalyzed efficient and chemoselective N-Boc protection of various amines using (Boc)(2)O is presented. Optically pure amino alcohols and amino acid esters were converted efficiently to their corresponding optically pure N-Boc derivatives. The reported method is mild, solvent-free and has the advantages of both homogeneous and heterogeneous catalysis with high product yields, selectivity and ease of product separation.

Deacetylative Amination of Acetyl Arenes and Alkanes with C–C Bond Cleavage
The Brønsted acid-catalyzedsynthesis of primary amines from acetyl arenes and alkanes with C–C bond cleavage is described. Although the conversion from an acetyl group to amine has traditionally required multiple steps, the method described herein, which uses an oxime reagent as an amino group source, achieves the transformation directly via domino transoximation/Beckmann rearrangement/Pinner reaction
