WebAug 4, 2024 · Bis-thiourea isomers were further characterized and confirmed by 1 H, and 13 C NMR. The proton chemical shifts of the amide functionality appeared as a singlet at δ 11.74 and 11.49 ppm for isomers 1A and 1B, respectively. The thioamide protons were observed as doublets at δ 11.24, 10.99 ppm for the isomers 1A and 1B, respectively. WebIn the title tri-substituted thiourea derivative, C13H18N2O3S, the thione-S and carbonyl-O atoms lie, to a first approximation, to the same side of the molecule [the S—C—N—C torsion angle is −49.3 (2)°]. The CN2S plane is almost planar (r.m.s.
