Initial studies of the effects of halogenated dispersions on the amount of NICS of rings for C8H12XNO2
Journal Title: International Journal of new Chemistry - Year 2017, Vol 4, Issue 1
Abstract
In this research at the first complex and its halogenated derivatives were optimized. NBO calculations and NMR for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level. In the 1- (4-fluorophenyl) -2, 3-dihydro-1 H-naphto- [1, 2-e] [1, 3] oxazine-3-n, there are 4 rings, respectively, rings from the side attached to the halogen They are named C, B, A, and D. 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 aromatize 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, this process was researched. In ring A, when halogens were changed, the increase in aromaticity in halogenated compounds was as follows: F> Cl> Br> I. The data in tables and graphs and shapes were compared and discussed.
