Synthatic pathway of bis phthaldicarboximide thion and isoimide via the reaction of phthalic anhydride with diamines

الملخص EN

Thio Bis-N, N substituted phthaldicarboximides were synthesized from the reaction of phthalic anhydride with diamines (aliphatic and aromatic) in hot acetic acid.

The products were treated with phosphorous pentasulphide N-substituted Phthalimidines were prepared by the reduction of N, N substituted phthaldicarboximide with zinc dust and hydrochloric acid in ether.

While isoimides was synthesis through the reaction of phthalic anhydride with diamines in the presence of trifloroacetic acid.
