Abstract

La réaction des époxydes 1–4 avec les nucléophiles a–f ne donne pas uniquement des aminoalcools siliciés mais aussi des azidoalcools avec TMSN3 et une chlorohydrine avec TMSCI. La réaction d'ouventure n'est possible qu'en présence d'acides de Lewis. Nous avons utilisé en quantité catalytique Bi(OTf)3 et BiCl3.
