Pentyl nitrate nitration with

The atmospheric lifetime of 2-pentyl nitrate with respect to reaction with OH radicals is calculated to be around 7 days using [OH] = i x 10 molecule cm and k = 1.7 X 10 cm molecule" s Loss via photolysis is also an important atmospheric fate for 2-pentyl nitrate with a photodissociation lifetime of about 4.5 days with an overhead Sun (see table IX-M-1). 

The ratio of two isomers of pentyl nitrate to pentane is compared with the ratio of butyl nitrate to butane in Figure 4. These two ratios are correlated. The solid line is the behavior expected from equation 1 with the... 

Pentyl nitrate in dry tetrahydrofuran with potassium terf-butoxide as condensing agent has proved particularly valuable 160,161 for instance, by this method adipodinitrile at —50° gives 93% of the 2,5-dinitro derivative, which can be worked up to give 1,4-dinitrobutane by hydrolysis and decarboxylation.161... 

Removal of aromatic phenotio groups is accomplished in 65-90% yield by conversion to the sulfonate, followed by catalytic hydrogenation. Aromatic arrrines are deaminated by aprotic diazotlzation with pentyl nitrate in yields up to 89%. ... 

Table VIII-D-14 gives the only available measurement of the rate coefficient for the reaction of Cl with -pentyl nitrate (Nielsen et al., 1991). This study was performed using a relative rate method at ambient temperature and atmospheric pressure.

Combining k(OH 1-pentyl nitrate) = 3.6 x 10 cm molecule" s with [OH] = 1x10 molecule cm provides an estimate of 3 days for the atmospheric lifetime of...

A comprehensive report has described the nitration of 3-hydroxy-1-phenyl pyrazoles [75JCS(P2)1609]. These hydroxy compounds are tautomeric with pyrazolones but at equilibrium the hydroxy form is favored. 3-Hydroxy-5-methyl-l-phenylpyrazole is nitrated in acetone using pentyl... 

To date, there has been no report of the nitrosation of imidazole itself. There are, however, a number of examples of nitrosation of substituted imidazoles in basic medium. The observation that such reactions do not occur with Af-substituted imidazoles implicates the imidazole anion as the likely substrate. Substitution generally occurs at C-4 or C-5 and may be accompanied by some nitration. In the presence of sodium ethoxide, pentyl nitrite nitrosates 4-phenyl-, 2-methyl-5-phenyl- and 2,5-diphenyl-imidazoles at the vacant 4- or 5-positions. The reaction apparently failed with 5-methyl-2-phenyl- and 4,5-diphenyl-imidazoles (58G463).
