Réactivité du 3,3-bis(triméthylsilyl)propène vis-à-vis des ions iminium issus dʹamines secondaires. Accès stéréosélectif à des (E)-β-aminovinylsilanes

The 3,3-bis(trimethylsilyl)propene reacts with iminium ions generated in situ from secondary amines by an aminomethylation–desilylation process, leading to (E)-β-aminovinylsilanes. When a secondary amine with two secondary groups is used, the reaction fails, the steric hindrance probably inhibiting the reaction.
