Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Australian Journal of Chemistry called Rates of N-methylation of N-methylpyrazole, isothiazole, and isoxazole and their 2,1-and 1,2-benzologs, Author is Davis, M.; Deady, L. W.; Homfeld, E., which mentions a compound: 271-95-4, SMILESS is C12=CC=CC=C1ON=C2, Molecular C7H5NO, Formula: C7H5NO.
The orders of quaternization of I, II, and III (X = NH, S, O) at 33° with MeI in Me2SO or with Me2SO4 were NH > S > O. Benzo fusion was usually rate diminishing; III (X = O) reacted faster than I (X = O).
