Efficient Synthesis of Novel Bis(dipyrromethanes) with Versatile Linkers <i>via</i> Indium(III) Chloride‐Catalyzed Condensation of Pyrrole and Dialdehydes

Abstract

Abstract A new efficient and mild protocol for synthesizing a series of novel bis(dipyrromethanes) with versatile arylene linkers through an indi‐ um(III) chloride‐catalyzed condensation reaction between various dialdehydes and pyrrole has been developed. This protocol is applicable to constructing a variety of bis(dipyrromethanes) with diverse functional linkers, which provides a powerful route to construct libraries of functionalized porphyrin dimers and even multiporphyrin arrays.
