Hydrazine monohydrate, 98+%, Thermo Scientific Chemicals

General References:

1. Forms stable, water-free solid complexes consisting of one hydrazine molecule associated with one molecule of hydroquinone or two molecules of 4-methoxyphenol. These have potential as replacements for the very hazardous anhydrous hydrazine, e.g. in the solid state reaction with esters to give pure hydrazides: J. Chem. Soc., Chem. Commun., 1531, (1995).
2. Diimide precursor: for generation of diimide by oxidation with O₂, and use in selective reduction of a double bond in the presence of a cyclopropane ring, see: J. Chem. Soc., Chem. Commun., 525 (1973). Review of diimide reductions: Org. React., 40, 91 (1991). See also Hydroxyl amine-O-sulfonic acid, A12560 .
3. In the Wolff-Kishner carbonyl to methylene reduction (heating with hydrazine and alkali hydroxide), diethylene glycol is now the usual solvent (the Huang Minlon modification): J. Am. Chem. Soc., 68, 2487 (1946); Org. Synth. Coll., 4, 510 (1963). The reduction has also been performed at ambient temperature by the use of KO-t-Bu in DMSO: J. Am. Chem. Soc., 84, 1734 (1962). See also Isatin, A12468 for an analogous reduction.
4. In the presence of Rh on carbon, nitrobenzene is selectively reduced to phenylhydroxylamine: Org. Synth. Coll., 8, 16 (1993).
