Oxidative 1,2-carboamination of alkenes with alkyl nitriles and amines toward γ-amino alkyl nitriles
Nature Communications, 2017 Difunctionalization of readily available alkenes is a powerful method to quickly build molecular complexity. Here the authors report a three-component, oxidative carboamination between alkenes, alkyl nitriles and amines, producingγ-amino alkyl nitriles.

Nickel-Catalyzed Reversible Functional Group Metathesis between Aryl Nitriles and Aryl Thioethers [PDF]
, 2020 We describe a new functional group metathesis between aryl nitriles and aryl thioethers. The catalytic manifold nickel/dcype is essential to achieve this fully reversible transformation in good to excellent yields. Furthermore, the cyanide and thiol-free

Ahmad-Strong synthesis of 8-, 9-, and 10-pentadecynoic acids
Journal of Lipid Research, 1969 Three pentadecynoic acids, with the triple bond in the 8-, 9-, and 10-positions, have been synthesized on a gram scale in over-all yield of 65% by refinements of the five-step Ahmad-Strong method; isolation of intermediates was shown to be unnecessary ...

Cyclic Nitriles: Diastereoselective Alkylations
, 2016 Diastereoselective alkylations of metalated conformationally locked 4-tert-butylcyclohexanecarbonitrile are highly diastereoselective with magnesium and copper counterions but only modestly diastereoselective with lithium as the counterion.
