Iminoesters amides

Photolysis of 3-methyl-1,2-benzisoxazole in n-hexane/acetonitrile produced a salicyl-amide. In contrast, photolysis in acetonitrile/methanol (95 5) gave an iminoester which subsequently hydrolyzed to methyl salicylate (Scheme 11) (74HCA376). [Pg.16]

V-Aminoazoles, for instance 1, react with nitriles or iminoesters to yield amidines 294 (69JPR477 71JPR768). The latter compounds were also obtained on amination of the Schiff bases with potassium amide in liquid ammonia (70JPR669). [Pg.166]

The hydrolysis of coordinated nitriles has recently attracted some attention. A very facile hydrolysis of nitriles to the corresponding amides at platinum(IV) centers has been described.The complex [Cu(H2NCOCH2CONHNH2)Cl] is formed from the reaction NCCH2CONHNH2 the copper(II) both promotes the hydrolysis and is reduced to copper(I). The hydrolysis of 2-cyanopyridine to 2-pyridinecarboxamide is accelerated several hundred times by the copper(II) complexes of the ligands (21) and (22). In the case of the (22) some picolinic acid was formed, resulting from the intramolecular attack of alkoxide to yield an intermediate iminoester. ... [Pg.286]
