Abstract

Carbon‐13 NMR spectra of 24 new N‐carboxyalkyl‐ and N‐alkoxycarbonylalkylsubstituted derivatives of (E)‐4‐styrylpyridine and (E)‐4‐o(m‐ or p)hydroxystyrylpyridine bromides have been calculated and fully assigned. The Ai and AiK empirical parameters of the N‐carboxyalkyl, N‐alkoxycarbonylalkyl, N‐carboxyalkyl‐4‐vinylpyridyl and N‐alkoxycarbonylalkyl‐4‐vinylpyridyl groups were calculated for the prediction of the chemical shifts of substituted stytylpyridines.
