Abstract
Two isomers of 1-benzylidene-1,2,3,4-tetrahydronaphthalene have been synthesized by the Wittig reaction, and the crystal structure of the cis-isomer has been solved. The compound C17H16 crystallizes in the monoclinic space groupP21/n witha=9.796(2),b=5.490(5),c=23.215(3)Å,β=95.11(2)°, andZ=4. The structure was determined by direct methods, and refined by fullmatrix least squares toR=0.047 for 1104 reflections. The cyclohexenylidene ring has the unusual envelopecs2, 10 conformation.
