Abstract
The hypothesized racemate separation of cyclooctapyrroles with chiral figure eight conformations—and of metal complexes derived from these ligands—has been realized. The cyclooctapyrrole 1 (as hexadecaethyl derivative), which according to NMR analysis exhibits restricted mobility, and its binuclear palladium and copper complexes could be separated into stable enantiomers by preparative chromatography on a chiral phase. In the case of the palladium complex and the free ligand 1 it was also possible to determine the absolute configuration of the enantiomers.This publication has 0 references indexed in Scilit:
