Crystal structures of (E)-3-(furan-2-yl)-2-phenyl-N-tosylacrylamide and (E)-3-phenyl-2-(m-tolyl)-N-tosylacrylamide

Abstract

In the title N-tosyl­acryl­amide compounds, (I) and (II), the conformation about the C=C bond is E. In (I), the furan, phenyl and 4-methyl­benzene rings are inclined to the acryl­amide mean plane [–NH—C(= O)—C=C–] by 26.47 (11), 69.01 (8) and 82.49 (9)°, respectively. In (II), the phenyl, and 3-methyl and 4-methyl­benzene rings are inclined to the acryl­amide mean plane by 11.61 (10), 78.44 (10) and 78.24 (10)°, respectively. In the crystals of both compounds, mol­ecules are linked by pairs of N—H⋯O hydrogen bonds, forming inversion dimers with (8) ring motifs.
