The reductive coupling of imines in the presence of the lanthanide-originated zirconocene equivalent allows the synthesis of vicinal diamines or imidazolidines under mild conditions in good yields with high diastereoselectivity. (C) 2011 Elsevier Ltd. All rights reserved.
A Samarium “Soluble” Anode: A New Source of SmI2 Reagent for Electrosynthetic Application
An electrochemical method to prepare solutions of samarium diiodide in THF is reported. The simple electrolysis of a samarium rod provides a rapid and straightforward in situ synthesis of SmI2. The electrogenerated complex catalyzes various CC bond formations. The reagent is produced continuously (see scheme) and leads to efficient organic electrosynthesis with significantly smaller amounts of solvent
