Interaction of ions with carbonyl donors: 13C and 23Na nuclear magnetic resonance spectra
Abstract
The 13C n.m.r. spectra of a few carbonyl donors have been recorded in the presence of Li+, Na+, and Mg2+. The 13C resonances of carbonyl and other groups shift downfield on interaction with the ions. The solvation numbers of Na+ with acetone and cyclohexanone have been determined from 23Na n.m.r. spectra.
