—— | 3-fluoro-6,12-dibromochrysene | 1092475-10-9 | C18H9Br2F | 404.076 |
The photocyclization-oxidation reaction of 1,6-di-p-substituted-phenyl-1,3,5-hexatrienes gave 3,9-disubstituted-chrysenes. Similarly, irradiation of 1-p-substituted-phenyl-6-phenyl-1,3,5-hexatrienes yielded 3-substituted-chrysenes. The 3-substituted-chrysenes were independently prepared in a high yield by the photocyclization-oxidation of 1-α-naphthyl-2-p-substituted-phenylethylenes.
