Well-Defined Ruthenium Olefin Metathesis Catalysts: Mechanism and Activity
Abstract
Several ruthenium-based olefin metathesis catalysts of the formula (PR 3 ) 2 X 2 Ru CHCHCPh 2 have been synthesized, and relative catalyst activities were determined by monitoring the ring-closing metathesis of the acyclic diene diethyl diallylmalonate. The following order of increasing activity was determined: X = I < Br < Cl and PR 3 = PPh 3 ≪ P i Pr 2 Ph < PCy 2 Ph < P i Pr 3 < PCy 3 . Additional studies were conducted with the catalyst (PCy 3 ) 2 Cl 2 Ru CH 2 to probe the mechanism of olefin metathesis by this class of catalysts. The data support a scheme in which there are two competing pathways: the dominant one in which a phosphine dissociates from the ruthenium center and a minor one in which both phosphines remain bound. Higher catalyst activites could be achieved by the addition of CuCl to the reaction.

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.
