ABSTRACT Synthesis Cyclic Compounds which are difficult to obtain in normal ways. Developing our in formation concerning the Synthesis of two new Bis-Phthalamic Compounds from reaction between diamines Aromatic Compounds with Phthalic anhydride and add new Compounds to (Compounds Isoimids) by Synthesis two new Bis-Phthalisoimids from adding reagent (DCC) to the Bis- Phthalamic and Studying and diagnosing them by Spectrally (I.R.) in addition to the accurate quantitative elemental analysis. Studying the thermal stability to yield compound and the antimicrobial activity of the synthesized compound was tested against Gram positive and Gram negative bacteria and some fungi. This method provides several advantages such as good yield, simple work-up procedure and environment friendly and have good effect upon some becteria and fungi.
