Crystal structure of 2-tert-butyl-2,3-dihydro-1H-benzo[c]pyrrol-1-one

Abstract

The asymmetric unit of the title compound, C12H15NO, comprises two symmetry-independent molecules which differ mainly in the conformations of the tert-butyl groups. The molecules contain an essentially planar five-membered 3-pyrroline ring incorporating a carbonyl substituent (pyrrolinone) which forms part of an isoindolinone skeleton. The planarity of the pyrrole ring is compared to other structures with isoindolinone. There are only weak intra- and intermolecular C—H...O and C—H...π-electron-ring interactions in the crystal structure.
