New aromatic diamine monomers prepared from condensation reactions of aniline, p-chloroaniline, p-nitro aniline, p-chloro-m-nitro aniline with 4-amino-N,N-dimethylaniline (2:1) (aniline:reagent) in the presence of potassium dichromate in acidic media yielded new monomers of a highly colored violet and reddish-violet. Mechanism of the reaction of an...

Due to the advantages of material abundance and synthetic simplicity, polyaniline can be used as a high capacity cathode material. However, its practical application in battery has been hindered by poor electrochemical utilization and cycling instability. To solve these problems, we synthesized the Polyaniline-co-o-nitroaniline aniline. The copolym...

Condensation reactions of aniline, benzidine, p-toluidine, p-anisidine with 4-amino-N, N-dimethylaniline (2:1) (aniline: reagent) in the presence of potassium dichromate in acidic media yielded condensation products of a highly colored violet and reddish-violet, and their identification was confirmed by IR, 1H-NMR, and CHN analyses.

4,6-Dimethyl2-pyrimidinethiol (DMPT) and 4,6-Dimethyl2-pyrimidineamine(DMPA) react with Alcl 3 to form poly(4,6-dimethylpyrimidinesulfide) (PDMPS), and poly(4,6-dimethylpyrimidineamine) (PDMPA).These are products of electrophilic substitution reaction of the Friedel-Crafts type.
