“…1. The 2-butenyl substituent at the imide N atom of the planar phthalimide adopts an antiperiplanar conformation with torsion angles C1-N1-C9-C10 and N1-C9-C10-C11 of 92.53 and -131.59 (1)°; to difference of the orientation synperiplanar of N-Allylphthalimide (Mustaphi et al, 2001;Warzecha, Lex & Griesbeck, 2006). The phthalimide ring system is essentially planar, with a maximum deviation of 0.008 (1)Å for atom C1 and dihedral angle of 0.13 to 1.39 (1)°, for other hand, the dihedral angle of 92.53 (1)° evidence that the N-crotyl group is orthogonal to the the phthalimide ring plane.…”

2-(3-Hydroxypropyl)isoindoline-1,3-dione: competition among hydrogen-bond acceptors

“…N-Substituted phthalimides, (I), are of interest for their biological activity in their own right (Lima et al, 2002) and as precursors for synthesis (Couture et al, 1998). Crystallographic studies have appeared recently in which the imide N atom bears a nonpolar substituent, such as ethyl, (Ia) (Liang & Li, 2006c), or allyl, (Ib) (Warzecha et al, 2006). Other studies have investigated the situation when an N-alkyl substituent terminates with a hydrogen-bond donor, including hydroxymethyl, (Ic) (Liang & Li, 2006a), hydroxyethyl, (Id ) (Liang & Li, 2006b), and a series of alkanoic acids, (Ie)-(Ii) (Feeder & Jones, 1996).…”
