- Pd(OAc)2-catalyzed dinitration reaction of aromatic amines
-
Taking advantage of Pd(OAc)2-catalyzed dinitration reactions with Bi(NO3)3·5H2O in trifluoroethanol (TFE) and trifluoroacetic acid (TFA), we have developed an efficient and practical method for the synthesis of secondary dinitro-aromatic amines. The products could be applied to the preparation of 5-amine-N-methyl-benzimidazolone, the azo-dyes, economic advantages. The method has also been expanded to the dinitration reaction of some tertiary aromatic amines.

- A novel N-N bond cleavage in 1,5-diaminotetrazole: Synthesis and characterization of 5-picrylamino-1,2,3,4-tetrazole (PAT)
-
The reaction of 1,5-diaminotetrazole with picryl chloride (PiCl) forms 5-picrylamino-1,2,3,4-tetrazole (PAT) rather than the expected 1-picrylamino-5-amino-1,2,3,4-tetrazole or 5-picrylamino-1-amino-1,2,3,4- tetrazole. The structure of PAT was confirmed by single-crystal X-ray diffraction. Some of the energetic properties of the synthesized compound were also studied.
