TL;DR: Iridium-catalyzed ring cleavage reaction of cyclobutanone O-benzoyloximes in the presence of 9,10-dihydroanthracene and potassium carbonate proceeds to give saturated nitriles via C-C bond fission at the sterically more hindered site.

TL;DR: Palladium-catalyzed transformation of cyclobutanone O-benzoyloximes to a variety of nitriles is described and the sequential reaction composed of the C-C bond cleavage and the subsequent intra- and intermolecular C- C bond formations via the corresponding alkylpalladium species is demonstrated.

TL;DR: The addition of terminal alkynes to acrylate esters in the presence of a ruthenium catalyst and chloride sources proceeds to give the corresponding γ,δ-alkynyl ester in good yields.
