Web26 mei 2024 · The nucleophilicity of triethylamine is less than that of diethyl amine largely because the triethylamine nitrogen is tertiary, which will increase steric hindrance and slow down the reaction rate. For this reason, formation of tertiary amines from secondary amines via alkylation is thus, for the most part, exempt from our broad “ amine alkylation is crap” …
