2,3-Dideuterioesters are obtained in high yield from 2-chloro-3-hydroxyesters by a sequenced elimination/reduction process promoted by samarium diiodide generated in situ from metallic samarium and diiodomethane.

Radicals produced via the indirect reduction of alkyl halides by aromatic radical anions are likely to couple fast with the mediator. In the presence of activated olefins or good hydrogen atom donors the fate of the alkyl radicals might be changed. In this study rate constants for the coupling reaction (2) between primary, secondary and tertiary alkyl radicals and some aromatic radical anions were measured via the competition with addition of the radical to styrene or ethyl cinnamate, or via the competition with hydrogen atom transfer from thiophenol or 2-methyl-2-propanethiol to the alkyl radical. It is shown that for all the alkyl radicals and aromatic radical anions investigated so far the rate constant for coupling is close to 1 × 109 M-1 s-1. Acta Chemica Scandinavica 1998.
