Mesomeric shifts of the types shown in structures (82) and (83) increase the electron density on the nitrogen atom and facilitate reaction with electrophilic reagents. However, the heteroatom Z also has an adverse inductive effect the pK, of NH2OH is 6.0 and that of N2H4 is 8.0, both considerably lower than that of NH3 which is 9.5. [Pg.49]

Amines are insufficiently nucleophilic to react with most azoles which do not contain a ring oxygen, and the stronger nucleophile NH2 is required. When treated with amide ions, thiazoles can be aminated in the 2-position by NaNHa at 150 °C. Only TV-substituted condensed imidazoles such as 1-alkylbenzimidazole react in such Chichibabin reactions. Imidazoles are aminated by alkaline NH2OH. [Pg.65]

Oxime (Section 17.10) A compound of the type R2C=NOH, formed by the reaction of hydroxylamine (NH2OH) with an aldehyde or a ketone. [Pg.1290]

Aqueous solutions of NH2OH can then be obtained by ion exchange, or the free compound can be prepared by ammonolysis with liquid NHj insoluble ammonium sulfate is filtered off and the excess of NHj removed under reduced pressure to leave solid NH2OH. [Pg.431]

Anhydrous NH2OH can be prepared by treating a suspension of hydroxylammonium chloride in butanol with NaOBu ... [Pg.432]
