Hydrocyanation 意味
WebL' hydrocyanation est une réaction d'addition d'un proton H + et d'un anion cyanure CN − sur un substrat, généralement un alcène, un alcyne ou un composé carbonylé, ce qui donne un nitrile –C≡N. Ce dernier peut ensuite être converti en d'autres groupes fonctionnels, par exemple amine primaire –CH 2 –NH 2 ou acide carboxylique –COOH. http://www.organicreactions.org/index.php?title=Hydrocyanation_of_alkenes_and_alkynes&mobileaction=toggle_view_mobile
