Nickel-catalyzed intermolecular codimerization of acrylates and alkynes.
The linear codimerization of acrylates and alkynes to produce 1,3-dienes is successfully demonstrated using a nickel catalyst in association with 2-aminopyridine as an additive.
متن کاملSelective synthesis of trienes and dienes via nickel-catalyzed intermolecular cotrimerization of acrylates and alkynes.
Tailoring nickel-catalyzed linear cotrimerization of acrylates and alkynes effectively proceeds to produce trienes and dienes highly selectively.
متن کاملNickel-catalyzed [4+2] cycloaddition for highly substituted arenes.
Nickel(0) catalyzed [4+2] cycloaddition of electron-deficient dienes to alkynes and subsequent aromatization gave highly substituted arenes. This formal inverse electron-demand Diels-Alder cycloaddition is attributed to the formation of a seven-membered nickelacycle from a diene and an alkyne.
متن کاملCatalytic defluorinative [3 + 2] cycloaddition of trifluoromethylalkenes with alkynes via reduction of nickel(II) fluoride species.
Nickel-catalyzed [3 + 2] cycloaddition of 2-trifluoromethyl-1-alkenes with alkynes via domino C-F bond activation was achieved by sequential β-fluorine elimination. The nickel(ii) fluoride species formed in this reaction was reduced by a diboron compound, regenerating the catalytically active nickel(0) species.
متن کاملNickel-Catalyzed Intramolecular [3 + 2 + 2] Cycloadditions of Alkylidenecyclopropanes. A Straightforward Entry to Fused 6,7,5-Tricyclic Systems
A highly diastereo- and chemoselective intramolecular nickel-catalyzed cycloaddition of alkene- and alkyne-tethered alkynylidenecyclopropanes is reported. The method constitutes the first fully intramolecular [3 + 2 + 2] alkylidenecyclopropropane cycloaddition occurring via a proximal cleavage of the cyclopropane and makes it possible to build relevant 6,7,5-tricyclic frameworks in a single-pot...
