N-Benzyl-4-(4,4-diphenylbuta-1,3-dienyl)-N-ethylaniline

The title compound, C31H29N or PhCH2(Et)NC6H4CH=CHCH=CPh2, was synthesized by the Wittig–Horner reaction between 4-(N-benzyl-N-eth­yl)amino­benzaldehyde and the phospho­nate carbanion, derived from 1,1-diphenyl-3-chloro­propyl­ene and triethyl phosphite by the Arbuzov reaction. The butadiene fragment has a planar transoid conformation.
