M-Nitrobenzyl alcohol

Potassium and sodium borohydride show greater selectivity in action than lithium aluminium hydride thus ketones or aldehydes may be reduced to alcohols whilst the cyano, nitro, amido and carbalkoxy groups remain unaffected. Furthermore, the reagent may be used in aqueous or aqueous-alcoholic solution. One simple application of its use will be described, viz., the reduction of m-nitrobenzaldehyde to m-nitrobenzyl alcohol ... [Pg.881]

Remove most of the methanol by distillation on a steam bath, and dilute the residue with 100 ml. of water. Extract the mixture with ether, wash the upper layer with water, and dry it rapidly with a little anhydrous magnesium sulphate. Remove the ether by flash distillation, and distil the residual pale yellow oil under diminished pressure. Collect the m-nitrobenzyl alcohol at 183-185°/17 mm. it solidifies to a pale yellow solid, m.p. 30°, when cooled in ice. The yield is 13 g. [Pg.881]

Successful mass spectrometry of concave acids and bases was possible in most cases by El, 70 eV. But in some cases, only other MS techniques gave molecular peaks field desorption [12a] FAB-MS (m-nitrobenzyl alcohol) [27b] El, 12eV [28]... [Pg.98]

Fast-atom bombardment (FAB) and liquid secondary-ion mass spectrometry (LSIMS) methods make up the category of the particle bombardment ionization. In both methods the analyte is dissolved in a liquid such as glycerol, thioglycerol, m-nitrobenzyl alcohol, or diethanolamine and about 1 1 is placed on a... [Pg.713]

Cognate preparation. m-Nitrobenzyl alcohol. Clamp a 500-ml three-necked flask, equipped with a mechanical stirrer, a thermometer and a burette, above the bench so that an ice bath can be placed beneath it. Place a solution of 15.1 g (0.1 mol) of m-nitrobenzaldehyde (Expt 6.19) in 100 ml of methanol in the flask and, while stirring, add a solution of sodium borohydride (1.4g, 0.037 mol NaBH4 in 2 ml of 2 m sodium hydroxide diluted with 18 ml of water) at the rate of 0.5 ml per minute, with occasional cooling to keep the reaction at 18-25 °C. When about three-quarters of the solution has been added, there is no further tendency for the temperature to rise, and the addition is stopped. Treat a small portion of the reaction mixture with dilute sulphuric acid hydrogen should be evolved. [Pg.524]

The mechanism of ESI continues to be a fascinating topic, which continues to raise research interest and efforts, as for instance indicated by the observation of higher charge states with enhanced abundance via the addition of glycerol or m-nitrobenzyl alcohol to the ESI solvent [29]. [Pg.447]

Wan and Yates [56] reported the photochemical oxidation of m-nitrobenzyl alcohol in aqueous solution to m-nitrobenzaldehyde and azoxy compounds. [Pg.78]
