| abstract |
1-(O-),2-((PYRID-2-YL)-CH(-CH3)-CH2-),3-((-)O-)-2- IMIDAZOLINIUM ACIDITY DETERINATIONS ARE MADE FROM VARIATIONS IN ELECTRON SPIN RESONANCE (ESR) SPECTRA WITH COMPOUNDS HAVING AN ASYMMETRIC CENTER BONDED THROUGH A METHYLENE GROUP TO AN ORGANIC FUNCTIONALITY HAVING AN UNPAIRED ELECTRON. ACCURATE DETERMINATION OF ACIDITY CAN BE MADE BY COMPARING THE SPECTRUM OF THE SAMPLE BEING MEASURED TO A STANDARD. |
