Method for preparing hydroxylamines using vinylic compounds without base neutralization and reaction mixture produced thereby |
摘要 |
Substituted hydroxylamines useful in photographic processing solution can be prepared by reacting a hydroxylamine with a vinylic compound having an electron withdrawing substituent in a suitable solvent, in the absence of a neutralizing base. The resulting products can be used without isolation from the reaction solution.
