Reduction of Ag(I) by 1-acyl-2-arylhydrazines: Mechanism of photographic infectious development

W. Russell Bowman; J. Anthony Forshaw; Kevin Peter Hall; Jonathan P. Kitchin; Andrew W. Mott

Abstract The photographic process of ‘infectious development’ in which 1-acyl-2-arylhydrazines reduce Ag(I) has been studied using analogues. 1-Acyl-2-aryldiazenes, resulting from oxidation of 1-acyl-2-arylhydrazines, are hydrolysed to anions of aryldiazenes (ArN=NH), which undergo further oxidation with loss of nitrogen to yield aryl radicals. The aryl radicals cause ‘feedback inhibition’ which is prevented by the addition of benzhydrol.
