suzuki reaction | [Definition]
ChEBI: Azetidine is a saturated organic heteromonocyclic parent, a member of azetidines and an azacycloalkane. | [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. | [Synthesis]
To a 1-liter conical flask was added 4.0 mol of azetidine hydrochloride and 280 g of water, and the mixture was stirred at 20 degrees Celsius until the solid was dissolved, then to a 2-liter four-necked round-bottomed flask was added 230
g of water to wh | [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.
