Photoirradiation of tris(2-benzo[b]thienyl)methane in acetonitrile resulted in the unexpected formation of a cyclopropane compound, which is rationalized based on the di-π-methanerearrangement including two unsaturated bonds of the benzo[b]thiophene rings.
三(2-苯并[ b ]噻吩基)甲烷在乙腈中的光辐照导致意外形成环丙烷化合物,这是基于包括苯并[ b ]噻吩环的两个不饱和键的二-π-甲烷重排而合理化的。
