摘要

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 C 17 H 16 crystallizes in the monoclinic space group P 2 1/n with a= 9.796 (2), b= 5.490 (5), c= 23.215 (3) Å, β= 95.11 (2)°, and Z= 4. The structure was determined by direct methods, and refined by fullmatrix least squares to R= 0.047 for 1104 ...
