To 40 mL of the above solution of crude fluorodinitroethylcarbamoyl chloride 626, 2-fluoro-2,2-dinitroethanol 630 (5.6 g) was added, followed, dropwise and with cooling in an ice bath, by pyridine (3.1 g). The mixture was stirred at room temperature for 2 h, diluted with dichloromethane (100 mL), washed with dUute sulfuric acid, dried, and concentrated. Repeated chilling, filtration, and concentration of the mother liquor gave several fractions of N,0-his(2-Jluoro-2,2-dinitroethyl)-carbamate 631 containing diminishing amounts of N,N -bis(2-fluoro-2,2-dinitro-ethyl)urea as an impurity. The yield of crude product amounted to 3 g. The product was purified by recrystallization from dichloromethane/hexane mp 63-64 °C. 

Heat together under very efficient water reflux 1 g. of freshly fused dry powdered ZnClg, 2 ml. of diethyl ether and 0 5 g. of 3,5 -dinitrobenzoyl chloride for 2 hours. Shake the product with 5 ml. of water and ther add 10% NaOH solution until all the ZnCl, and excess of 3,5-dinitro> benzoyl chloride and 3,5-dinitrobenzoic acid have gone into solution. Filter at the pump and recrystallise from petroleum (b.p. 40-60°) to obtain ethyl 3,5-dinitrobenzoate, m.p. 93°. (M ps. of other 3,5 dinitro-benzoates, p. 536.)...

Of the crystalline derivatives of thiols, those formed with 3 5-dinitro-benzoyl chloride are not very satisfactory since they have, in general lower melting points than those of the corresponding alcohols (compare Section 111,27,7) and do not diflfer widely from ethyl to n-heptyl. The best results are obtained with 2 4-dinitrochlorobenzene. 

The benzoyl compounds frequently occlude traces of unchanged benzoyl chloride, which thus escape hydrolysis by the caustic alkali it is therefore advisable, wherever possible, to recrystaUise the benzoyl derivatives from methyl, or ethyl alcohol or methylated spirit, since these solvents will esterify the unchanged chloride and so remove the latter from the recrystalKsed material. Sometimes the benzoyl compound does not crystallise well this difficulty may frequently be overcome by the use of p-nitrobenzoyl chloride or 3 5-dinitro-benzoyl chloride, which usually give highly crystalline derivatives of high melting point (see Section IV,114j.

However, other studies on the nitration of a series of 3-methyl- and 3-ethyl-1,2-benzisoxazoles have shown that a mixture of the 5-nitro and 5,7-dinitro derivatives is formed (77IJC(B)1058, 77IJC(B)1061). The effect of substituents in the benzene ring is also of interest. If the 5-position is blocked, e.g. by a chloro group or by alkyl groups, nitration then occurs at the 4-position. 3-Alkyl-7-chloro and 3,7-dialkyl derivatives result in the formation of the appropriate 5-nitro derivative. The isomeric 3-alkyl-6-chloro- and 3,6-dialkyl-1,2-benzisoxazoles yield a mixture of the 5-nitro and 5,7-dinitro compounds. Both H NMR measurements and alternate syntheses were used in establishing the structures of these substitution products. 

The compounds 87a and 87b are aminated at position 4, yielding the 4-amino compound (88a, 40%) and the 2,4-diamino compound (88b, 11%) respectively the 2-ethoxy compound (87c), however, undergoes amination at position 4 as well at position 5, giving a mixture of the 4-amino compound (88c, 20%) and the 5-amino compound (89a, 14%).Tlie 2-chloro compound (87d) yields a highly complex reaction mixture from which the 5-amino compound (89b), the 2,4-diamino derivative (88b), and 2,5-diamino-l,8-naphthyridine (89c) could be isolated. l-Ethyl-3-nitro-l,8-naphthyridin-2(lH)-one (90a) and 3,6-dinitro-l-ethyl-l,8-naphthyridin-2(lH)-one (90b) were aminated exclusively in the 4-position to give compounds 91a (62%) and 91b (45%), respectively (93LA471). 

Excellent yields of the oximes of phenylacetaldehydes are obtained by reduction of 6-nitrostyrenes over Pd-on-C in a pyridine solvent (74,75). The technique gives yields of only about 60% when applied to aliphatic unsaturated nitrocompounds better yields are obtained in acidic media(6 5). Over 5% Rh-on-Al203 in ethanol-acetic acid-ethyl acetate, 2- 6-dinitro-styrenes are converted to 2-nitrophenylacetaldehyde oximes (13). 

Isolation of Citronellal and Citral. At the close of each experiment (7 to 10 days), the nests were frozen intact. Groups of 200 workers were placed in a micro-Soxhlet apparatus and extracted for 8 hours with methylene chloride. A few milligrams of carrier citronellal and citral were added and the mixture was applied to a thin-layer chromatoplate (silica gel G) which was developed with hexane-ethyl acetate (92 to 8) to separate citronellal and citral (3). The aldehydes were detected by spraying with a solution of 2, 4-dini-trophenylhydrazine in tetrahydrofuran (20) and the citronellal and citral peaks were scraped off and allowed to react with excess dinitro-phenylhydrazine reagent for a further 12 hours.
