Unusual Nitrile–Nitrile and Nitrile–Alkyne Coupling of FcCN and FcCCCN

Chemistry – A European Journal, 2014
AbstractInvited for the cover of this issue is the group of Uwe Rosenthal at Leibniz Institute for Catalysis (LIKAT Rostock) and the group of Heinrich Lang at the Technische Universität Chemnitz. The image depicts five coupling possibilities of alkynes and nitriles at metallocenes. Read the full text of the article at 10.1002/chem.201304478.

Cobalt-Catalyzed Selective Hydrogenation of Nitriles to Secondary Imines.

Organic Letters, 2018
The first example of cobalt-catalyzed selective hydrogenation of nitriles to secondary imines is reported. The results demonstrate the significantly different selectivity compared with the previously reported cobalt catalytic system during the nitrile ...

Nitrile Ylide Dimerization:  Investigation of the Carbene Reactivity of Nitrile Ylides

The Journal of Organic Chemistry, 2004
A series of novel hexaaryl diazatrienes 5 ("nitrile ylide dimers") were synthesized directly from the corresponding diaryl ketimines 12 and dichlorotoluenes 13 in a facile one-pot synthesis. The carbene character of the nitrile ylides was investigated by varying the substituents on the aromatic ring adjacent to the carbene center.

Activation of nitriles by hydrogen bonding in cycloadditions with nitrile oxides

Journal of Heterocyclic Chemistry, 1984
AbstractThe dipolarophilic activity of aromatic nitriles in cycloaddition with benzonitrile oxides is remarkably enhanced by ortho‐acylamino substituents. The activation depends upon the solvent and can be ascribed to a hydrogen bond which assists cycloaddition.

Cycloadditions of Donor–Acceptor Cyclopropanes and Nitriles

, 2017
Lewis acid promoted cycloaddition reactions of donor–acceptor (DA) cyclopropanes are one of the well-studied approaches for the construction of heterocyclic and carbocyclic frameworks.

Selective Hydrogenation of Nitriles to Primary Amines by using a Cobalt Phosphine Catalyst.

ChemSusChem, 2017
A general procedure for the catalytic hydrogenation of nitriles to primary amines by using a non-noble metal-based system is presented. Co(acac)3 in combination with tris[2-(dicyclohexylphosphino)ethyl]phosphine efficiently catalyzes the selective ...

Copper-Catalyzed [2+2+2] Modular Synthesis of Multisubstituted Pyridines: Alkenylation of Nitriles with Vinyliodonium Salts.

Angewandte Chemie, 2017
A [2+2+2] modular synthesis of multisubstituted pyridines, with excellent regioselectivity, has been realized by copper catalysisand involves three distinct components: vinyliodonium salts, nitriles, and alkynes.
