✦ Synopsis


=C NMR spectra of some bifunctional nitrones containing the aldonitrone hctionality 8s part of the hetero-1,3-diene system have been determined, and interpreted for the chemical shifts and coupling constants. The steric slructures and long-range substituent effects on the heteroene carbon resonances are diSCusSed.

## Abstract Carbon‐13 chemical shifts of three arylmethyl carbanions have been determined by changing solvents and counter ions. The charge distributions in the carbanions are discussed and compared with those obtained from the ^1^H chemical shifts.
