5-苯基戊-2,4-二烯醛 | 5-phenylpenta-2,4-dienal | 13466-40-5 | C11H10O | 158.2 |
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.
