Propynyl group

This article is about a functional group. For the phenethylamine, see Propynyl (psychedelic).
Chemical structure of the 2-propynyl (propargyl) group.

In organic chemistry, a propynyl group is a propyl bearing a triple bond.[1]

  • The 1-propynyl group has the structure CH3-C≡C–R.[2]
  • The 2-propynyl group is also known as a propargyl group, and has the structure HC≡C−CH2–R.[3]
