Macrocyclic and Acyclic Molecules Synthesized from Dipyrrolylmethanes: Receptors for Anions
摘要:
A new class of macrocyclic and acyclic molecules was synthesized by the Mannich reactions of dipyrrolylmethanes to investigate anion recognition. The X-ray structures of the macrocycle and sulfate complexes are reported.

series of monoanions BF4−, Cl−, PhCOO− and ClO4−, and their X-ray structures showed that the ring conformation constitutes the 1,2-alternate form. Upon binding with dianions SO42−, CrO42−, SiF62− and S2O32−, the ring conformation changes to the cone conformation. The intermediate partial cone conformation results for complexes with NO3− and Cr2O72− ions. The change in the orientation of the pyrrole NH
