sterically hindered amines Explanation: E' sottinteso: stericamente impedite. Concetto di stereochimica. Posto che le ammine hanno la formula generale NR3, dove R puo' essere H o un gruppo alchilico o arilico ecc., se i gruppo alchilico o arilico e' voluminoso, per esempio -C6H5, esso scherma l'atomo d'azoto centrale (con carica parziale negativa) rendendo piu' difficile l'attacco da parte di un reagente. |
