- Synthesis method of nitramide
-
The invention relates to a synthesis method of nitramide. The method comprises the step of enabling an aniline reaction substrate and a nitrating reagent to be subjected to a reaction in a solvent at20-60 DEG C for 2-8 hours to obtain the nitramide, where

- Synthesis and properties of secondary N-nitroamines
-
Secondary arylamines and related compounds can readily be converted into the corresponding N-nitroamines by treatment of their organomagnesium derivatives with butyl nitrate. The yield of the products ranges from 45 to 77%. Secondary aromatic N-nitroamine

- Direct Nitration of Anilines Using Nitrocyclohexadienones
-
Nitrocyclohexadienones (in particular, 2,3,5,6-tetrabromo-4-methyl-4-nitro-2,5-cyclohexadienone) are used as reagents for the direct nitration of anilines.Depending on the conditions, good yields of C-nitroanilines are obtained.Under the same conditions, N,N-dimethylaniline is converted into N-methyl-N-nitroaniline.

- SUBSTITUENT EFFECT TREATMENT OF INTERACTIONS BETWEEN CONTIGUOUS FUNCTIONALITIES. IV. RESTRAINT TO PHENYL-NITROGEN CONJUGATIVE INTERACTION IN N-FUNCTIONALIZED N-METHYLANILINES
-
13C shifts at the para position in PhN(Me)X for 17 different substituents X serve as monitors for investigating, in correlative analysis, the nature and the extent of interactions occurring between the substituent X and the N-Me cavity.For the majority of substituent, X, partitioning of the nitrogen electron pair between the phenyl and the substituent is partially hampered because of the non-zero twist angle between the planes containing the phenyl ring and the Me-N-X fragment.As a consequence, relative to PhNHX, the interactions between the cavity and the substituents are increased in intensity, especially their mesomeric component, and, at the same time, para-13C shifts are displaced toward lower field.Evidence is also provided that possible H-bonding by the NH cavity of PhNHX with dimethyl sulphoxide does not appreciably influence the substituent electron demand determined previously.
