Propylamine

Overview

Propan-1-amine, a primary amine with a three-carbon chain.

The NH2 group is attached to a terminal carbon. Protonation produces a propylammonium salt, while acylation can give an N-propylamide. Reduction of propanenitrile retains all three carbons, including the original nitrile carbon adjacent to nitrogen.

Connected reactions

• Nitrile reduction: Propanenitrile → Propylamine

  Hydride additions reduce the carbon-nitrogen triple bond; the separate aqueous work-up protonates the nitrogen-containing intermediates. The nitrile carbon becomes CH2NH2, preserving the enlarged three-carbon skeleton.
