Sažetak
An a-deuterium isotope effect kH/kn of 170/o was found in the
E 2 reaction of 2-phenylethyl-l,l-d2 bromide with sodium ethoxide
in ethanol. This supports the Streitwieser change-of-hybridization
theory and the associated explanation of the absence of such effects
in S N2 reactions as being due to the proximity of the incoming
group. The magnitude of the ~- and a-deuterium isotope effects in the
SNl and E2 reactions of some alkylsulphonium salts were determined
and compared with the isotope effects of the corresponding
alkyl-halides. An explanation for these differences is given.
