Abstract

The ^3^Δ‐deuterium isotope effects of partially and fully deuteriated tert‐butyl groups on the ^13^C NMR spectra of tert‐butylbenzene and derivatives are discussed in detail. It is shown that they correlate with the chemical shift of C‐1 of the aromatic ring. It has been demonstrated that when deuterium is replaced with some other substituents, the SCS values of these substituents show a parallel behaviour to the deuterium isotope effects. It is concluded that, for the compounds studied, deuterium isotope effects and substituent chemical shifts can be described on a common basis.

Deuterium-induced isotope effects on 13C chemical shifts were measured in a series of benzene derivatives, viz. toluene, benzoic acid and benzophenone. The effects over two, three and four bonds reflect a dependence on the transmission pathway and the nature of the side-chain. Steric and inductive i
