The relationship of bisanthranil to its structural isomer and related compounds
Abstract
A spectroscopic, mass spectroscopic, and chemical examination of bisanthranil, m. p. 185°, and of its structural isomer, m. p. 302°, has confirmed the lactone structure of the former and the amide structure of the latter. The spectra were compared with those of 2-phenylindazol-3-one, 2-(2-carboxyphenyl)indazol-3-one, 2-phenyl-3,1-benzoxazin-4-one, isatoic anhydride, and dianthranilide.
