5-Bromo-1-methylindolin-2-one

Abstract

The title molecule, C9H8BrNO, approximates a full planar conformation. The interplanar angle between the benzene and five-membered rings of the indoline system is 1.38 (1)°. There is an obvious π-delocalization involving the N—C=O group in the five-membered ring, which is greater than that involving the N—C...;C(benzene) group.
