Hmm. What do you do when you realize (based on your own work and some deduction related to part of the molecule described) that something someone showed in a talk and published in a paper is extremely likely to be completely artifactual?
It's a minor issue, and unlikely to be field-defining or anything, so it's not like some major dogma needs to be unseated here. But the poor scientists who are working on this will likely continue to study this artifact, and it makes me sad because they are very nice people who are genuinely excited about this thing they think it novel and useful.
I mean, maybe it's not an artifact--we'd have to do the experiment to find out. But if it is...
