3-Methyl-1-(prop-2-en-1-yl)quinoxalin-2(1H)-one

Abstract

In the molecule of the title compound, C12H12N 2O, the quinoxaline ring is planar with an r.m.s. deviation of 0.007 (15) Å. The dihedral angle between the quinoxaline and propenyl planes is 82.1 (2)°. The crystal packing is stabilized by offset π-π stacking between the quinoxaline rings [centroid-centroid distance = 3.8832 (9) Å].
