In the title compound, C16H21NO2, the indoline ring and the two ketone O atoms are approximately coplanar, the largest deviation from the mean plane being 0.063 (2) Å. The mean plane through the fused ring system is nearly perpendicular to the mean plane passing through the 1-octyl chain [dihedral angle = 77.53 (17)°]. In the crystal, molecules are linked by C—H⋯O hydrogen bonds, forming a three-dimensional network.
The crystal structure of the title compound, C16H24N2O, is built up from two fused six- and five-membered rings linked to C9H19 chains. The fused-ring system is essentially planar, the largest deviation from the mean plane being 0.009 (2) Å. The chain is nearly perpendicular to this plane [dihedral angle = 80.27 (17)°]. In the crystal, intermolecular N—H⋯O hydrogen bonds form dimers with an R

2(8) graph-set motif. These dimers are further connected through C—H⋯O hydrogen bonds, building sheets parallel to (100).
ABSTRACT:In this paper, anovel cationic surfactant is synthesized by the alkylation reaction of 5-Chloro-1H-indole-2,3-dioneunder the conditions of phase transfer catalysis and quaternizationby trimethylamine in acetone solution.Chemical structures of synthesized compounds were confirmed by 1 HNMR and 13 C NMR. The micellization of cationic surfactant in aqueous solution at room temperature has been reported using the conductivity of the measurements
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
