Azetidine Usage And Synthesis
Chemical Properties clear colorless liquid
Uses suzuki reaction
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.
