1,4-Diallylquinoxaline-2,3(1H,4H)-dione

Abstract

The structure of the title compound, C14H14N2O2, has been established. The plane formed by the atoms of the quinoxaline is almost perpendicular to the two allyl groups.

1,4-Dihydroxyquinoxaline-2,3(1H,4H)-dione

“…The quinoxaline ring is planar, which can be attributed to a wide range of electron delocalization. Bond lengths and angles are in accordance with the corresponding reported values in 1,4-dihydroquinoxaline -2,3-dione core (Oxtoby et al, 2005) and other similar N-alkyl quinoxalines (Akkurt et al, 2004;Mustaphi et al, 2001). The existence of (I) in the dione form is evident from C1-O2 [1.226 (3) Å] bond, being smaller than a pure single bond, which confirms the double bond character (Allen et al, 1987 typical for the corresponding single and double bonds, suggesting some degree of delocalization.…”

N-Allylphthalimide: parallel ribbons ofR(10) motifs crosslinked by Cvinyl—H...O bonds

“…1; relevant geometric parameters are summarized in Table 1. The allylic substituent at the imide N atom of the planar phthalimide adopts a synperiplanar conformation; a similar orientation has been reported for 1,4-diallylquinoxaline-2,3(1H,4H)-dione (Mustaphi et al, 2001). In (I), the allyl group is orthogonal to the the phthalimide ring plane.…”
