Abstract

^13^C chemical shifts and ^31^P,^13^C coupling constants are reported for nine 1‐hydroxyalkylphosphonic and two additional phosphonic acids. The α‐substituent‐induced chemical shifts (α‐SCS) of the phosphonate group were calculated and their non‐additivity was observed. Good linear correlations exist between the chemical shifts and also between the α‐SCS parameters of 1‐hydroxyalkylphosphonic acids and the respective values of analogously constituted 1‐aminoalkylphosphonic acids.

NMR chemical shifts for some a-heterosubstituted acetones were recorded. The carbonyl carbon shieldings are discussed in the light of the substituent electronic effects and were also empirically estimated by Tanaka et d ? s equation.

Exchange of amide protons with deuterium results in changes of 13 C chemical shifts for carbon atoms near the site of substitution (CH{N and N{C|O). There is a measurable decrease in the isotopic shifts of CH{N for cycloalkylacetamides as ring size increases from 3 to 8 and for lactams as ring size

The "C NMR spectra of nine dichlorinated bicyclo[2.2.l]heptanes (norbornanes) have been measured and assigned. The pairwise effects of chlorine substituents which cause deviations from the additivity of single-snbstituent effects were investigated and are discussed. The largest effect found is the h
