16“…The N—C(aryl) bond length [1.4225 (14) Å] is intermediate between that in N-phenyl-tert-butanesulfinamide [1.4083 (12) Å] and the N—C(alkyl) bond lengths in N-alkylalkanesulfinamides (1.470–1.530 Å), suggesting weaker delocalization of electrons over the N atom and the aromatic ring due to the presence of the 4-methoxy group.…”

19“…The title Schiff base compound, C(9)H(12)N(2)O(2), was obtained from a condensation reaction of butan-2-one and furan-2-carbohydrazide. The furan ring and the hydrazide fragment are roughly planar, the largest deviation from the mean plane being 0.069 (2)Å, but the butanylidene group is twisted slightly with respect to this plane by a dihedral angle of 5.2 (3)°. …”
