One of these reactions forms a hydrozone intermediate and relies on the expulsion of nitrogen gas; Huang Minlon found that that reaction could be sped up by distillation. Reagents such as lithium aluminum hydride are often used (10[1])for this class of (10[1])reactions. (10[1])Carbonyls (10[1])are converted to alkanes via this class of reactions, two of which are named for Clemmensen and Wolff–Kishner. A reaction of this type that traditionally employs sodium and ammonia was developed by Birch. Unlike (10[1])their counterpart, these reactions often add hydrogen or remove oxygen atoms. For 10 points, name these reactions which result in the gain of electrons for a chemical species, contrasted with oxidation. ■END■
