Structural evidence of halogenated 3-(4-alkylphenyl)-4-thioxo-2H-1,3-benzoxazine-2(3H)-ones and 3-(4-alkylphenyl)-1,3-benzoxazine-2,4-(3H)-dithiones

Abstrakt

The 1H- and 13C- NMR spectra were used to structural evidence of halogenated 3-(4-alkylphenyl)-4-thioxo-2H-1,3-benzoxazine-2(3H)-ones and 3-(4-alkylphenyl)-1,3-benzoxazine-2,4-(3H)-dithiones. There results of elemental analysis are in the good agreement with the predicted structure of compounds.
