Abstract

Certain imines lead to the formation of imidazolidinederivative in THF with Sm/TiCl₄ 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.

Key words: samarium, titanium tetrachloride, imine, imidazolidine derivative
