It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
Phenoxy-and benzyloxypropynyl alcohols of the phosphinane series are synthesized. The steric structure of individual isomers is established by means of 1 H and 13 C NMR spectroscopy. Stereodirection of the ethynylation of trans- and cis -2,5-dimethyl-1-phenyl-2-thioxo-λ 5 -phosphinane-4-ones is studied.
