Synthesis and Crystal Structure of 1,1-Dimethoxy-4,4-bis(phenylamino)-3-buten-2-one

Abstract

The crystal structure of 1,1-dimethoxy-4,4-bis(phenylamino)-3-buten-2-one (I) has been determined. There are two symmetrically independent molecules in the crystal lattice with some differences in the bond lengths, angles and torsion angles. The nitrogen atoms are nearly planar and π-delocalization exists in I. In the crystal structure, two different parallel infinite chains are produced by N-H…O hydrogen bonds, each of them containing one of the two independent molecules.
