Photoirradiation of tris(2-benzo[b]thienyl)methyl alcohol in acetonitrile afforded a cyclopentanone compound and a benzo[b]thiophene-condensed tropone derivative. The former is interpreted to originate via the di-π-methanerearrangement using the unsaturated bonds in two thiophene rings, while the latter via trimerization of the unsaturated bonds in three thiophene rings.
在乙腈中对三(2-苯并[ b ]噻吩基)甲醇进行光辐照,得到环戊酮化合物和苯并[ b ]噻吩缩合的托酮衍生物。前者被解释为通过使用两个噻吩环中的不饱和键进行二-π-甲烷重排而产生,而后者则是通过三个噻吩环中的不饱和键的三聚而产生的。
