Theoretical and experimental study of the orientational nitrogen lone-pair effect on 1J(13C13C) couplings in acetoxime
The difference between 1Jcc(Z) and 1Jcc (E) for acetoxime is experimentally and theoretically studied as a nitrogen lone-pair orientational effect. Experimentally, it is observed that this difference almost disappears upon full protonation. Theoretically, the most recent version of the IPPP program...

The difference between 1Jcc(Z) and 1Jcc (E) for acetoxime is experimentally and theoretically studied as a nitrogen lone-pair orientational effect. Experimentally, it is observed that this difference almost disappears upon full protonation. Theoretically, the most recent version of the IPPP program is used, finding that the N lone pair contributes to the couplings a positive component for 1Jcc(Z) and a negative one for 1Jcc(E), which are found to be the main cause of this difference. © 1989. |
