—— | 6,12-dibromo-3-cyanochrysene | 1092366-20-5 | C19H9Br2N | 411.095 |
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.
