  摘要：

  1-Alkoxy-3,5-dinitrobenzenes were nitrated to give 1-alkoxy-2,3,5-trinitrobenzenes. The reaction of the latter with guanidine affords N-(2-alkoxy-4,6-dinitrophenyl)guanidines, which undergo cyclization under the action of KOH to form 5-alkoxy-3-amino-7-nitro-1,2,4-benzotriazine 1-oxides.

• Dual reactivity of 1-chloro- and 1-bromo-3,5-dinitrobenzenes in aromatic nucleophilic substitution

  Aromatic nucleophilic substitution reactions in 1-halo-3,5-dinitrobenzenes (where the halogen is bromine or chlorine) can occur with replacement of either a nitro group or a halogen atom, depending on the nature of anionic nucleophile Nu– as a Lewis base (hard, soft or intermediate), as well as on the polarity of the dipolar aprotic solvent.

  根据阴离子亲核试剂Nu–作为路易斯碱的性质，在1-卤代3,5-二硝基苯（卤素为溴或氯）中发生芳香亲核取代反应，同时取代硝基或卤素原子（硬，软或中间）以及偶极非质子溶剂的极性。
• Direct Amination of 1-Substituted 3,5-Dinitrobenzenes by 1,1,1-Trimethylhydrazinium Iodide

  The amination of 1-X-3,5-dinitrobenzenes via the vicarious nucleophilic substitution of hydrogen (VNS) with 1,1,1-trimethylhydrazinium iodide (TMHI) in the presence of t-BuOK or NaOMe in DMSO was studied. It was observed (when X = OMe, OCH2CF3, OCH2CF2CF2H, OPh) that the amination occurs regioselectively (ratio of ortho/pares-isomers is similar to9:1) and with high yield. For X = SPh or SCH2Ph, the reaction proceeded with a low yield (less than 20%), with a ratio of ortho/pares-isomers approximate to 1:1. For X = PhSO2 and 2 equiv of TMHI, a double amination occurs and 2,4-diamino-3,5dinitro-1-phenylsulfonylbenzene predominates in the mixture of isomers. Under the same conditions, 1,3,5-trinitrobenzene undergoes a double amination to yield 2,4diamino-1,3,5-trinitrobenzene. A proposed mechanism for this reaction is discussed.

  A number of 7-polyfluoroalkoxy-1,5-dinitro-3-azabicyclo[3.3.1]non-6-enes were synthesized by reduction of 3,5-dinitrophenyl polyfluoroalkyl ethers with sodium tetrahydridoborate, followed by the Mannich reaction with formaldehyde and primary amines.
