Synthesis and structure of 6-chloro-2,3-trimethylene-4-phenylquinoline

摘要

An X-ray structural investigation of 6-chloro- 2,3-trimethylene-4- phe nylquinoli ne obtained by the reaction of 2-amino-5-chlorobenzophenone with cyclopentanone was carried out. At 20 °C, a = 23.750,b= 9,242, c = 14.018 A, β = 112,68° space group (21c,Z= 8, 2647 reflections,R= 0.047 He five-membered ring has an envelope conformation Conjugation between the quinohne fragment and the phenyl substituent is significantly distorted dm to the rotation of the latter by -62
