for α-olefination of nitriles using secondary alcohols with the liberation of molecular hydrogen and water as the only byproducts is reported. This reaction is catalyzed by a molecularly defined manganese(I) pincer complex and operates in the absence of any hydrogen acceptors. A broad range of substrates including cyclic, acyclic, and benzylic alcohols, as well as various nitrile derivatives, such as
Ruthenium(II) pincer-catalyzed α-olefination of nitriles is reported. This simple protocol provides a transformation for the catalyticsynthesis of β-disubstituted vinyl nitriles using secondary alcohols. This catalytic method has an extensive substrate scope, as arylmethyl nitriles, heteroarylmethyl nitriles, and aliphatic nitriles as well as cyclic, acyclic, symmetrical, and unsymmetrical secondary
The use of 2-phenyl-2-alkene nitriles as fragrance ingredients and fragrance applications comprising them. These fragrance applications can be e.g. perfumes, household products, laundry products, body care products and cosmetics.
