Magnesium amide potassium nitrite

The popularity of the Nef reaction is due in part to the ready availability of nitro compounds. Primary and secondary halides react with sodium nitrite in dimeAyl sulfoxide (DMSO) or dimethylform-amide (DMF) to give useful yields of nitro compounds. Primary amines can be oxidized to nitro compounds with potassium permanganate, m-chloroperbenzoic acitP or ozone. Chlorination of oximes with hypochlorous acid and reduction with magnesium, zinc or hydrogen/lpalladium gives secondary nitro compounds. Stabilized carbanions can be nitrated by treauitent with a nitrate ester, and enol acetates are nitrated by acetyl nitrate to give nitro ketones. ... [Pg.218]

PHENYLIC ACID (108-95-2) C HjOH Combustible solid, smelt (molten), or liquid [explosion limits in air (% by volume when heated) 3 to 10 flash point 174°F/79°C autoignition temp 1319°F/715°C Fire Rating 2]. Violent reaction with butadiene, strong oxidizers. Reacts, possibly violently, with strong acids caustics, aliphatic amines amides, oxidizers, calcium hypochlorite formaldehyde, lead diacetate menthol, P-naphthol, peroxydisulfuric acid peroxymonosulfuric acid potassium hydroxide sodium nitrite 1,2,3-trihydroxybenzene. Liquid attacks some plastics, rubber and coatings hot liquid attacks aluminum, magnesium, lead, and zinc. On small fires, use CO2 or dry chemical extinguishers. [Pg.856]
