Synthesis and X-ray structural investigation of 6-chloro-10-phenyl-1,2,3,4-tetrahydroacridine

An X-ray structural study of 6-chloro-10-phenyl-1,2,3,4-tetrahydroacridine prepared by the reaction of cyclohexanone with 2-amino-5-chlorobenzofenone was carried out. At 20°Ca=24.215(6),b=8.967(2),c=15.006(3) Å, =115.57(2)°,V= 2939(1) ų,d _calc=1.310 g cm^–3,Z=4, space groupC2/c, 1324 reflections, MoK,R=0.038. The cyclohexene ring has a half-chair conformation. The phenyl substituent is rotated 71.2° with respect to the plane of the quinoline fragment.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 8, pp. 1467–1468, August, 1994.
