| Azetidine Usage And Synthesis |
| Chemical Properties | clear colorless liquid | | Uses | suzuki reaction | | Uses | Azetidine is involved in a high yielding palladium-catalyzed cross-coupling reaction with aryl bromides. Further, it is used in Ullmann type coupling reaction with iodonitroflourenes. In addition to this, it reacts with bis-(3-amino-propyl)-amine to prepare N,N'-bis-(3-amino-propyl)-propanediyldiamine using palladium as a catalyst. | | General Description | Phototransformations of azetidine radical cations in freonic matrices under the action of light with λ = 436nm has been investigated. The IR spectrum of azetidine in solid argon matrices has been measured. | | Purification Methods | Azetidine is a flammable, hygroscopic liquid smelling of ammonia, which absorbs CO2 from air and should be kept under Argon. Purify it by drying it over solid KOH and distilling it through a short Vigreux column (p 11) at atmospheric pressure (under Argon) and keeping the pot temperature below 210o. It is moisture sensitive. The hydrochloride M 93.6 has m > 300o and the hydroiodide has m 146.5o(from EtOH). The N-Me derivative has m 112o(from *C6H6/pet ether), and the Nphenylcarbamoyl derivative has m 189-190o(from EtOH). [Searles et al.
