Problems solved by technology

[0002] Breaking σ-σ bonds or coupling σ-σ bonds between pyridine rings is very important in the synthesis of compounds, but due to the high stability of pyridine rings, it is very difficult to break σ-σ bonds or couple σ-σ bonds between pyridine rings Yes, scientists have been looking for suitable reaction conditions, but so far, there are few reports on σ-σ bond breaking or σ-σ bond coupling between pyridine rings, and the reaction conditions are harsh (such as high temperature, noble metal catalyst, etc.)
According to the literature review, there is no report on the synthesis of compounds based on the simultaneous occurrence of σ-σ bond breaking and σ-σ bond coupling between pyridines under this condition
