Data confidence 70 medium
How this score is calculated

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.

Abstract

The catalytic activity of the Pd(PPh 3 ) 4 -TsOH and Pd(PPh 3 ) 4 -PPh 3 -TsOH systems in the reaction of isobutylene hydromenthoxycarbonylation with carbon monoxide and l -menthol has been examined. It has been found that the reaction proceeds regioselectively yielding the linear product l -menthyl isovalerate. Optimal conditions have been found for running the process. The spatial structure of l -menthyl isovalerate synthesized via the isobutylene hydromenthoxycarbonylation reaction has been established by 1 H and 13 C NMR techniques.
