Alkyl halides Potassium permanganate

C) Ammonolysis of Alkyl Halides. Place 20 ml of a saturated alcoholic solution of ammonia in methanol (90 per cent) in each of two test tubes. To the first add 2 g of n-amyl bromide, and to the second 2 g of amyl bromide. Cork, shake, label, and set aside until the following laboratory period. Add to each reaction mixture 20 ml of water, and separate the upper layer of amine (and imchanged halide). Test two drops of each product for amy-lene by shaking with 2 ml of 0.1% potassium permanganate or bromine water. Record the observations. Place the sample of amine in the proper bottle provided by the instructor for future study. 

From the alkyl 2,4-dinitrophenyl thioether (prepared from the alkyl halide as above) in glacial acetic acid, with aqueous potassium permanganate. 

Among the indirect methods of preparing aliphatic nitro compounds are the reaction of various alkyl halides with silver nitrite or sodium nitrite, the oxidation of oximes and amines with peroxy-trifluoroacetic acid, and the potassium permanganate oxidation of tertiary amines.
