(2E)-2-Benzylidene-4-ethyl-3,4-dihydronaphthalen-1(2H)-one

Abstract

In the title compound, C19H18O, the exocyclic C=C double bond has an E configuration. The ethyl substituent on the cyclohexanone ring is in an axial position. The cyclohexanone ring adopts a half-chair conformation, presumably due to conjugation in the benzene ring.
