Structure Determinations

Nitration of the bromophenols (4a) and (5a) give products of nitro-debromination . Reaction of 6-methyl-4-nitro-2-phenylphenol (5c) with nitrogen dioxide gives 2-hydroxy-2-phenylcyclohex-3-enones (8) and (9), and probably stereoisomers (10), (20), (21) and (22). The mode of ormation of these compounds is discussed. X-ray crystal structure determinations are reported for compounds (8) and (9).

The X-ray crystal structure determination of 4-t-butyl-r-2-(4'-t-butyl-2',6'-dimethylphenoxy)-t-6- hydroxy-2,6-dimethyl-t-5-nitrocyclohex-3-enone (3) is reported. This compound is formed by reaction of 4-t-butyl-2,6-dimethylphenol(1) with nitrogen dioxide (1 mol) in benzene, followed by removal of the benzene under reduced pressure.

Ion Recombination

Photolysis of the phenanthrene/tetranitromethane charge-transfer complex yields the triad of phenanthrene radical cation, nitrogen dioxide, and trinitromethanide ion. Recombination of this triad in dichloromethane at 20° gives 9-nitrophenanthrene (1), trans-10-trinitromethyl-9,10-dihydrophenanthren-9-yl nitrate (2a), trans-9-nitro-10-trinitromethyl-9,10-dihydrophenanthrene (2b), and trans-10-trinitromethyl-9,10-dihydrophenanthren-9-ol (2c). Adduct formation is partially suppressed when trifluoroacetic acid (0.7 M) is added to the dichloromethane solvent at 20°, the major product identified being 9-nitrophenanthrene (1). At -20° in dichloromethane, or in acetonitrile at 20°, 10'-nitro-9,9',10,10'-tetrahydro-9,9'-biphenanthren-10-yl nitrate (3) is formed, apparently by reaction of nitrogen dioxide with phenanthrene. X-Ray crystal structure determinations are reported for adducts (2a,b).

Product Yields

Reaction of phenanthrene (1) with nitrogen dioxide in benzene solution gives the dimeric nitro nitrate (3), trans and cis nitro nitrates (7) and (8), and 9-nitro- (4), 3-nitro- (5) and 1-nitro-phenanthrene (6). The X-ray crystal structure of the trans nitro nitrate (7) is reported. The effect of the phenanthrene (1) concentration on product yields is reported. Gas-liquid chromatography results for the nitro nitrates (3) and (7) point to difficulties in using this technique for product analyses in reactions of phenanthrene (1) with nitrogen dioxide.

2,2,N-Trimethyl-N-phenyl-2H-azirin-3-amine (1a) was prepared by successive treatment of 2,N-dimethyl-N-phenylpropanamide (18) with phosgene, triethylamine, and sodium azide. Reaction of 1a in THF solution with boron trifluoride gave 2-amino-1,3,3-trimethyl-3H-indolium tetrafluoroborate (19) in high yield.T he latter reacted with acetic anhydride in pyridine to give a mixture of N-(2,3-dihydro-1,3,3-trimethylindol-2-yliden)acetamide (22) and 2,3-dihydro- 1,3,3-trimethylindol-2-one (21).On hydrolysis with aqueous HCl, 22 was converted to 21.T he molecular structures of 19 and 22 were established by X-ray crystal structure determination.
