General description

Product may polymerize over time during storage.

Application

3-Oxetanone can be used to synthesize:
  • Various oxetane-containing lead compounds with improved solubility, reduced lipophilicity and amphiphilicity.
  • (Hydroxymethyl)oxazoles and (hydroxymethyl)thiazoles via single-step microwave mediated reaction with primary amides and thioamides, respectively.
  • Oxetane containing spirocycles through thermal 1,3-dipolar cycloaddition reaction with α-amino acids or secondary α-amino acid esters.

The pyrolysis products of gas-phase 3-oxetanone were identified via matrix-isolation Fourier transform infrared spectroscopy and photoionization mass spectrometry. Pyrolysis was conducted in a hyperthermal nozzle at temperatures from 100 to 1200 °C with the dissociation onset observed at ∼600 °C.
