Synthesis of novel metallocene bis(crown ethers). Potassium selective intramolecular sandwich-type complexation observed by fast atom bombardment mass spectrometry
Two new novel metallocene bis(crown ethers) have been prepared exhibiting exclusive K+ selective intramolecular sandwich-type complexation over either Na+ or Cs+; this has been observed by fast atom bombardment (f.a.b.) mass spectrometry.
