Copolymerization of oxetane with 3, 3-dimethyloxetane-I. Reactivity parameters and microstructure of the copolymers.

Bucquoye M and Goethals EJ.

Eur. Polymer J., 14(5), 323-328 (1978)

Mild one-step synthesis of dibromo compounds from cyclic ethers.

Peter Billing et al.

The Journal of organic chemistry, 77(24), 11227-11231 (2012-11-16)

A novel one-step method for mildly converting cyclic ethers into dibromo compounds is reported. Alcohols, oximes, aldehydes, and ketones are known to react under Appel or Corey-Fuchs reaction conditions, but apparently these have never been applied to oxetanes or larger

Cyclic oligomers in the cationic polymerization of 3, 3-dimethyloxetane.
