Double Dehydrogenation of Primary Amines to Nitriles by a Ruthenium Complex Featuring Pyrazole Functionality.

Journal of the American Chemical Society, 2018
A ruthenium(II) complex bearing a naphthyridine-functionalized pyrazole ligand catalyzes oxidant-free and acceptorless selective double dehydrogenation of primary amines to nitriles at moderate temperature. The role of the proton-responsive entity on the

Natural nitriles and their metabolism

World Journal of Microbiology & Biotechnology, 1990
The present work reviews the numerous nitrile compounds that have been isolated from plants and animals. Two kinds of potentially toxic molecules are widespread, namely the cyanogenic glycosides and cyanollpids. Many other aromatic and allphatic nitriles are synthesized to a lesser extent.

Manganese Catalyzed α-Alkylation of Nitriles with Primary Alcohols

, 2018
The manganese(I) complex bearing a bidentate hydrazone ligand efficiently catalyzes the α-alkylations of nitrile using primary alcohols as alkylating agents. α-Functionalized nitriles were selectively obtained in good to excellent yields. The reaction is

Comparison of Nitrile Gloves and Nitrile over Nomex Gloves

Air Medical Journal, 2009
Aeromedical flight crews must perform many tasks in flight requiring manual dexterity and fine precision. A common perception is that safety-enhancing fire-retardant gloves compromise patient care if worn during such tasks by providing added bulk and barrier to the hand.

Manganese Catalyzed α-Olefination of Nitriles by Primary Alcohols.

Journal of the American Chemical Society, 2017
Catalytic α-olefination of nitriles using primary alcohols, via dehydrogenative coupling of alcohols with nitriles, is presented. The reaction is catalyzed by a pincer complex of an earth-abundant metal (manganese), in the absence of any additives, base,
