Efficient synthesis of tertiary amine by direct <i>N</i>-alkylation of secondary amine with carboxylic acid using Ni (0) encat catalyst QuadriSyed Aziz Imam DasTonmoy C. JadhavShivaji FarooquiMazahar 2018 <p>In this article, direct <i>N</i>-alkylation of secondary amines with carboxylic acid is described. Readily available diversified carboxylic acid has been explored on variant secondary amines using encapsulated Nickel as catalyst and inexpensive sodium borohydride as the hydride source. High yields, mild reaction conditions, tolerance to sensitive functional group and facile operational procedure are the significance of the present methodology.</p>
