(E)-N-(3,4-Di-methyl-phen-yl)-1-[5-(phenyl-ethyn-yl)thio-phen-2-yl]methanimine

摘要

The title compound, C 21 H 17 NS, was synthesized via the reaction of 5-(2-phenyl-eth-1-yn-yl)thio-phene-2-carbaldehyde and 3,4-di-methyl-aniline using ammonium bifluoride (NH 4 HF 2 ) as an acid catalyst in methanol. The mol-ecule has three aryl rings: a phenyl (A), a thio-phene (B), and a di-methyl-benzene ring (C). The dihedral angles between the mean planes defined by these individual rings are 14.88?(6)° for A/B and 43.93?(4)° for B/C.
