Azetidine, also called trimethyleneimine is the simplest nitrogen-containing saturated four-membered heterocycle. It forms the basic structure of the group of azetidines.

Representation

Azetidin can be obtained from the thermal conversion of 1,3-diaminopropane with hydrochloric acid.

Properties

Azetidine is a colorless liquid with a boiling point of 61-62 ° C. It is a heterocyclic nitrogen base.

Reactions

The azetidine ring can be opened by nucleophiles. This makes possible the synthesis of terminal amines.

For example, ethylenediamine reacts with the palladium catalyst azetidine ring opening to a triamine.
