PMR spectra and deutero exchange in certain esters of chloronitroacetic acid

PMR spectra and deutero exchange in certain esters of chloronitroacetic acid

A series of chloronitroacetic acid (CNAA) esters was investigated and their PMR spectra studied in a pure state, and in solutions of CDCl/sub 3/, CO(CD/sub 3/)/sub 2/, and SO(CD/sub 3/)/sub 2/ at concentrations of from 5 to 50%. The effect of isotope exchange between the ester protons and deuteroace...

Zusammenfassung:A series of chloronitroacetic acid (CNAA) esters was investigated and their PMR spectra studied in a pure state, and in solutions of CDCl/sub 3/, CO(CD/sub 3/)/sub 2/, and SO(CD/sub 3/)/sub 2/ at concentrations of from 5 to 50%. The effect of isotope exchange between the ester protons and deuteroacetone was observed. The kinetics of the deutero-exchange were studied. A possible mechanism of the deutero-exchange is discussed.
