The first example of the nickel-catalyzed tandem addition/cyclization of 2-(cyanomethyl)benzonitriles with arylboronic acids in 2-MeTHF has been developed, which provides the facile synthesis of aminoisoquinolines with good functional group tolerance under mild conditions. This chemistry has also been successfully applied to the synthesis of isoquinolones by the tandem reaction of methyl 2-(cyanomethyl)benzoates with arylboronic acids. The use of the bio-based and green solvent 2-MeTHF as the reaction medium makes the synthesis process environmentally benign. The synthetic utility of this chemistry is also indicated by the synthesis of biologically active molecules.
Aminoisoquinolines as colorimetric Hg2+ sensors: the importance of molecular structure and sacrificial base

experimental part, p. 4293 - 4297 (2009/10/09)
Here it is shown that 3-phenyl-2-amino isoquinoline acts as a simple mercury sensor. It is simple to synthesize. The molecule requires base/buffer to bind in a 1:1 stoichiometry with mercury ion, however. Otherwise, it acts as a sacrificial base, presumab
Displacement of Halogen of 2-Halogeno-Substituted Benzonitriles with Carbanions. Preparation of (2-Cyanoaryl)arylacetonitriles

(2-Cyanoaryl)arylacetonitriles are obtained by displacement of halogen of 2-halobenzonitriles with phenylacetonitrile anions.The method also applies to a number of heteroaromatics with ortho-situated halogen and cyano groups and to heteroarylacetonitrile anions.The anions were generated by using potassium tert-butoxide or potassium carbonate.Calculated electron densities of the electrophilic centers reflect the reactivity in the displacement reaction.The calculations indicate that the potassium ion complexes with the cyano group of the 2-halobenzonitriles in nonpolar solvents, thus promoting competitive addition of the anion to the cyano group.Carbanions derived from acids with pKa ca. 19-23 similarly displaced the halogen of 2-halobenzonitriles.
