The step iii reaction most probably proceeds via an ene-type mechanism similar to the conversion of 480 to 481, apparently without requirement for light, with 3O2 rather than 1O2 as the active species.
“This reaction most probably proceeds via an “ene-type” mechanism similar to that for the conversion of 480 to 481, although apparently without the requirement for light (i.e. 3O2 rather than 1O2 is perhaps the active species) [193,236,304,305].”

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.
