Facile Synthesis of Unsubstituted β,β′-Linked Diformyldipyrromethanes
摘要:
Unsubstituted beta,beta'-linked diformyldipyrromethanes are promising precursors for the synthesis of novel poly dipyrromethene ligands and N-confused porphyrins. A strategy has been developed to selectively synthesize unsubstituted beta,beta'-linked diformyldipyrromethanes in moderate yields starting from 2-formylpyrrole.

materials science, development of methods for preparation of fluorinated arenes is of high importance. They can be either accessed by arene fluorination or by partial arene defluorination. However, the carbonfluorine bond belongs to the strongest σ‐bonds, which renders CF activation highly challenging. Here it is shown that aryl and alkyl isonitriles efficiently activate the strong CF bond in perfluoroarenes
