Oxidative cyclization of open chain thiabilanes yielded the first examples of unique piperazine bridged thianorrole dimers instead of the expected thianorrole monomer. In the thianorrole dimer, the two thianorrole monomeric units are linked via two direct pyrrole C-C bonds by involving the inverted pyrrole and adjacent pyrrole rings of each thianorrole macrocycle and generate a six-membered piperazine ring that bridges the two thianorrole macrocycles. The spectral studies indicated that the thianorrole dimers are nonaromatic in nature.
开链硫杂双环烷的氧化环化得到了独特的哌嗪桥联硫杂茂二聚体的首例实例，而不是预期的硫杂茂单体。在硫杂茂二聚体中，两个硫杂茂单体单元通过涉及每个硫杂茂大环的反式吡咯和相邻吡咯环的两个直接吡咯 C-C 键连接，并生成桥接两个硫杂茂大环的六元哌嗪环。光谱研究表明，硫杂茂二聚体在性质上是非芳香族的。
