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.

A pair of triple-stranded helicates and mesocates were, for the first time, isolated from the same reaction of a novel α-free bis(dipyrromethene) ligand with either Co3+ or Fe3+.
