| Abstract: | A new dicondensed compound,4-(2-methylene-1-ethyl-3,3-dimethylindoline-2′-yl)-6,8-dichloro1′-ethyl-3′,3′-dimethylspiro3,4-dihydro-2 H-1-benzopyran-2,2′-indoline],was prepared by the reaction of excess Fischer base with 3,5-dichlorosalicylaldehyde in ethanol.The structure of the compound was determined by melting point test,elemental analysis,IR spectroscopy and X-ray diffraction analysis.The results showed that the compound belongs to monoclinic system,space group P21/n with a=1.2889(3),b =1.2395(3),c=1.9362(4)nm,β=106.86(3)°,V =2.9603(13)nm3,Z=4,F(000)=1160,Dc= 1.228g/cm3,μ=0.247mm-1. |
