Nickel-Catalyzed Decarboxylative Carboamination of Alkynes with Isatoic Anhydrides
TL;DR: An intermolecular nickel-catalyzed addition reaction in which isatoic anhydrides react with alkynes to afford substituted quinolones has been developed and a mechanistic rationale is proposed, implying oxidative addition of Ni(0) to a carbamate, which allows intermolescular addition to alkynes via decarboxylation.
Journal ArticleDOI
Syntheses, structures and properties of 1-ethyl-3-methylimidazolium salts of fluorocomplex anions.

TL;DR: In this article, a room-temperature ionic liquid, 1-ethyl-3-methylimidazolium fluorohydrogenate (EMIm(HF)2.3F, EMIm = 1-methyl-3methyloridazolate cation), and Lewis fluoroacids (BF3, PF5, Asf5, NbF5, TaF5 and WF6) gave EMIm salts of the corresponding fluorocomplex anions, including EMImBF4, EMIMPF6, EMAsF6
Journal ArticleDOI
Nickel-Catalyzed Cycloaddition of o-Arylcarboxybenzonitriles and Alkynes via Cleavage of Two Carbon–Carbon σ Bonds
TL;DR: An intermolecular cycloaddition reaction has been developed, where o-arylcarboxybenzonitriles react with alkynes to afford coumarins in the presence of Ni(0)/P(CH(2)Ph)(3)/MAD as a catalyst.
Journal ArticleDOI
Lanthanoid Triflate Catalyzed Conjugate Addition of Amines to α, β-Unsaturated Esters. A Facile Route to Optically Active β-Lactam
TL;DR: The reaction of benzylamine with α,β-unsaturated esters containing a stereogenic center at γ-position proceeded diastereoselectivity to yield optically active β-lactam precursors as mentioned in this paper.
Journal ArticleDOI
Cationic iron(III) porphyrin-catalyzed [4 + 2] cycloaddition of unactivated aldehydes with simple dienes.
TL;DR: Cationic iron(III) porphyrin was found to be an efficient catalyst for the highly chemoselective hetero-Diels-Alder-type reaction of aldehydes with 1,3-dienes and the potential utility of the catalyst was demonstrated.
