| Abstract: | The electroreduction of 1–3 diphenylpropenone (chalcone) in anhydrous DMF, on a mercury pool, leads to a new trimer compound or some classical hydrodimers. The former was obtained with TBA+ as a counter ion and its configuration completely solved. The latter were obtained in the presence of Li+, Cr3+ or Mn2+ and their structures were determined unambiguously for the first time. In all cases the influence of the counter ion on the distribution of products was reported. |
