Asymmetric addition of pyridine to 1,4-bis(ethynyl)bicyclo 2.2.2 octane: dissymmetrical rotator ligands illustrated in dpppPt(II) and Re6Se8 (2+) complexes and an amphidynamic hydrogen bonded framework solid

摘要

A polar function like pyridine increases the polarity difference between mono- and disubstituted 1,4-bis(trimethylsilylethynyl)bicyclo[2.2.2] octane cores allowing for their ready separation by chromatography, affording two dissymmetrical ligands illustrated in metal-rotor hybrids like a corner-shaped mononuclear complex, an octahedral hexanuclear metal complex, and a framework solid with a rather slow rotator.
