Abstract

The efficient formation of cyclic polyesters from the ring‐opening polymerization of lactide, ϵ‐caprolactone, and β‐butyrolactone catalyzed by a 1,4‐dithiabutanedyl‐2,2′‐bis(4,6‐dicumylphenol) [OSSO]‐FeCl complex activated with cyclohexene oxide was achieved. The catalyst was very active (initial turnover frequency up to 2718 h−1), robust, and worked with a monomer/Fe ratio up to 10 000. The formation of cyclic polymers was supported by using high‐resolution matrix‐assisted laser desorption ionization (MALDI) MS, and the average ring size (≈5 kDa for cyclic polylactide) independent of the reaction conditions. A monometallic ring‐opening polymerization/cyclization mechanism was proposed from the results of a kinetic investigation.

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.
