M. Largeron et al., RELATIONSHIP BETWEEN PYRIDINE NITROGEN BASICITY AND STERIC CROWDING IN AN N-SUBSTITUTED-3-METHOXYPICOLINAMIDE SERIES, Journal of chemical research. Synopses, (10), 1996, pp. 454-455
The determination of pyridine nitrogen basicity in an N-substituted-3-
methoxypicolinamide series was identified as a useful probe to evaluat
e the intensity of steric crowding at the amide nitrogen position.
