Triethylamine as a base
Did you know?
WebTriethylamine is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia. Triethylamine is commonly employed, usually as a base, in organic synthesis. Triethylamine anhydrous is a chemical compound that can be used as a catalyst for isocyanate reactions and as a neutralization agent for anionic stabilized waterborne resins. WebTriethylamine is useful if your compound is a base. I personally prefer dimethylethylamine in this case, because it's rotavaped in a jiffy, but it stinks worse than TEA. 1% of acetic acid or triethylamine is a nice amount for a first TLC run.
WebFigure 1. Schematic of the reaction between the AMPP derivatization reagent and carboxylic acids or aldehydes. (A) Reactions with carboxylic acids, in the presence of peptide coupling reagents, and (B) aldehydes yield covalently bound charged-tagged amides and Schiff bases, respectively. TEA: triethylamine. WebCorrect option is A) This is due to steric crowding which makes the approach and bonding by a proton more difficult i.e. the path is blocked due to the presence of three methyl groups. This decreases its basicity. Therefore, dimethylamine is a stronger base than triethylamine.
