Abstract

The kinetics of the Stille reaction between C6Cl 2F3I and PhCCSnBu3 have been studied for the whole catalytic system and for transmetalations as separate steps. The use of (trifluorodichlorophenyl)palladium derivatives slows down the reactions and allows for the observation of the intermediates cis-and trans-[Pd(C 6Cl2F3)I(PPh3)2]. The first is formed in the oxidative addition step and isomerizes to the second. Both were studied as catalysts for the whole cycle. The kinetic study compares the relevance of the transmetalation step on each isomer. The competing transmetalations produce both cis-and trans-[Pd(C6Cl 2F3)(PhCC)(PPh3)2]. The former undergoes very fast C-C coupling, while the second accumulates in solution due to extremely slow isomerization. Thus, the system is a case study of the effect of competing pathways in the Stille reaction and its consequences on the performance of the catalytic process. © 2011 American Chemical Society.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-03:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 49.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 49 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 3.
  • The number of mentions on Wikipedia: 3 (Altmetric).
