New Insights into the Mechanism of Ruthenium-Catalyzed Olefin Metathesis Reactions [PDF]
, 2001 Over the past two decades, olefin metathesis has emerged as a mild and efficient method for the formation of carbon−carbon double bonds. In particular, (PCy_3)_2(Cl)_2RuCHPh (1)^2 has found extensive use in organic and polymer chemistry due to its high ...

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application
European Journal of Organic Chemistry, EarlyView.Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Characterization and Dynamics of Substituted Ruthenacyclobutanes Relevant to the Olefin Cross-Metathesis Reaction [PDF]
, 2011 The reaction of the phosphonium alkylidene [(H_(2)IMes)RuCl2═CHP(Cy)_3)]^(+) BF_(4)^− with propene, 1-butene, and 1-hexene at −45 °C affords various substituted, metathesis-active ruthenacycles. These metallacycles were found to equilibrate over extended

European Journal of Organic Chemistry, EarlyView.The total synthesis of the manzamine alkaloid keramamine C (2) in its racemic form was achieved in 5 steps, with ring‐closing metathesis as the key step. The metathesis is strongly improved by an intramolecular H‐bond‐induced conformational fixation of the amide bond, inducing close proximity of the terminal double bonds in the precursor molecule.

Emerging Trends in Organic Photoreactions Utilizing Disulfides
European Journal of Organic Chemistry, EarlyView.Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...
