Abstract

The asymmetric unit of the title compound, C30H24N2O2, contains two independent mol­ecules, which both lie on centers of inversion. The central phenyl­ene ring is inclined at 61.4 (2)° with respect to the flanking aromatic ring [dihedral angle = 70.7 (3)° in the second mol­ecule].

Comment

1,4-Bis(4-aminophenoxy)benzene is a precusor for the synthesis of polyamides owing the functional amino –NH2 group that will condense with carboxylic acids (Shemsi et al., 2008). The amino group can be also converted to a dialkylamino group by reaction with an alkyl halide in the presence of potassium carbonate. This strategy is used for the synthesis of the nitrogen–propargyl bond. The unit cell has two independent molecules of C30H24N2O2 (Scheme I) that both lie on a center-of-inversion (Fig. 1). The central phenylene ring is aligned at 61.4 (2) ° with respect to the flanking aromatic ring (the dihedral angle is 70.7 (3) ° for the second molecule). There is only one reported example of the nitrogen-parpargyl bond (Steiner et al., 1999).

Experimental

1,4-Bis(4-aminophenoxy)benzene (1 g, 2.2 mmol) was dissolved in ethanl (30 ml) followed by the addition of potassium carbonate (3 g, 21 mmol). The mixture was heated for 1 h. Propargyl bromide (1.5 ml, 15 mmol) was added and the heating was continued for another 8 h. The solvent was evaporated under reduced pressure and the residue was dissolved in a mixture of water (50 ml) and dichloromethane (50 ml). The aqueous layer was extracted three times with dichloromethane and concentrated. The product was recrystallized from ethanol; yield 60%.

Refinement

Carbon-bound H-atoms were placed in calculated positions [C—H 0.95 to 0.99 Å, Uiso(H) 1.2Ueq(C)] and were included in the refinement in the riding model approximation.

The acetylenic H-atoms were located in a difference Fourier map, and were refined with a distance restraint of C–H 0.95±0.01 Å; their temperature factors were refined.
