Through a nickel-catalysed Heck-type reaction, a direct coupling of alkenes with α-cyano alkyl bromides was achieved. This procedure provides a novel way for the synthesis of β,γ-unsaturated nitriles.

A highly efficient, organocatalytic, enantioselective Strecker reaction of cyclic N-acyl ketimines was developed for the preparation of enantioenriched cyclic α-amino nitriles with a quaternary carbon stereocentre and anti-HIV drug DPC 083.

The tandem hydroamination-annulation reaction of 4-pentyne-nitriles in the presence of amine nucleophiles and a cooperatively operating catalyst system, consisting of Ph(3)PAuCl and Zn(ClO(4))(2), provides an efficient route to 2-aminopyrroles. Two regioisomeric 2-aminopyrroles were formed in moderate to good yields.

The title compound C11H10BrN, has an E conformation at the C=C bond of the acrylo-nitrile unit. The vinyl group makes a dihedral angle of 44.53 (12)° with the benzene ring. In the crystal, weak C-H⋯π inter-actions involving the benzene ring are observed.

sulfuric acid {[3-(3-silicapropyl)sulfanyl]propyl}ester (saspspe) is employed as a recyclable catalyst for the synthesis of α-amino nitriles. these syntheses were performed via a one-pot three-component condensation of aldehydes, amines, and trimethylsilyl cyanide under mild reaction conditions at room temperature. the catalyst could be recycled and reused several times without any loss of effi...

The hydration numbers of typical aprotic polar substances bearing dipole moments larger than 3 D, such as nitro compounds and nitriles, were precisely determined in aqueous solution using high frequency dielectric relaxation techniques up to a frequency of 50 GHz at 25 °C. The hydration number is one of the most quantitative parameters for determining the hydrophilicity or hydrophobicity of a c...
