Calculations and studies show that the amount of aromatics in the halogen-ring A in all cases has the highest number. In the B loop, the predicted aromatism level is zero, and in the ring C and D, relative to the A loop, the aromaticity increase is as follows: A > D> C In the next stage of the study, with the replacement of the halogen ring A from F to I, the following process was observed.In ring A, when halogens were changed, the increase in aromaticity in halogenated compounds was as follows: F> Cl> Br> I %U https://www.ijnc.ir/article_35290_e92ea48fe851e4a870f694d6db55512d.pdf
