β¦ Synopsis
Depending on the experimental conditions the reaction of 5-substituted 2-amino-2-oxazolines 1 with acetic anhydridee led to acetylated compounds which exhibit or not an heterocyclic ring. The 5substituted 3-acetyl-2-oxazolidinones 4 were finally isolated in boiling acetic anhydride. Vol 3.

## Abstract Kinetic investigations on the cationic ringβopening polymerization of 2βethylβ2βoxazoline were conducted using acetyl chloride, acetyl bromide, and acetyl iodide as initiators. Various polymerization temperatures ranging from 80 to 220βΒ°C were applied under microwave irradiation. The re
