Kinetics and mechanism of the isomerization polymerization of 2‐methyl‐2‐oxazoline by benzyl chloride and bromide initiators. Effect of halogen counteranions

Saegusa, Takeo, Kobayashi, Shiro, Yamada, Akira·1976·Die Makromolekulare Chemie

Abstract

Abstract Kinetic studies of the isomerization polymerization of 2‐methyl‐2‐oxazoline (2) initiated with benzyl chloride (1a) or bromide (1b) were carried out by NMR spectroscopy. The polymerization initiated with 1a proceeded exclusively via a covalently bonded alkyl chloride species 5, whereas the polymerization of the system initiated with 1b proceeded via a oxazolinium bromide 10 as the propagating end. The propagation rate constant kp with 1a was about 1/40 of that found with 1b at 40°C in CD3CN. The mechanistic difference is explained by the different nucleophilicities of the counteranions, Cl— and Br—. A model compound for the propagation with 1b as initiator was also examined changing the temperature and the solvent.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
