Аннотация:
The basicity constants, K BH<sup>+</sup> , of 13 acetanilides have been evaluated in sulphuric acid at 25°. Recent evidence on the site of protonation of amides has been reviewed and a new equation for calculating pK BH<sup>+</sup> has been formulated. The values of pK BH<sup>+</sup> obtained for the para-substituted acetanilides correlate well with Hammett Ï values.
