| Abstract: | Certain imines lead to the formation of imidazolidine derivative in THF with Sm/TiCl 4 system. It was found that products of reductive coupling could be obtained in below 20% yields without 1,2 dibromoethane, while products of reductive coupling in moderate yields when 1,2 dibromoethane was added. The structures of all products were confirmed by IR, 1H NMR and MS spectra. According to the results of the experiment, a possible mechanism was proposed. |
