Web15 apr. 2006 · Preparative Methods: by treating diethylamine with Phenyllithium or n ‐Butyllithium or, alternatively, by treating diethylamine with Lithium metal in the presence of Hexamethylphosphoric Triamide 2 or an electron acceptor. 3 By treatment of the parent amine with lithium metal in THF using catalytic isoprene and ultrasound generated ... WebLithium 2,2,6,6-Tetramethylpiperidide (LiTMP, pKa. 37).[4, 8, 9] This is the most potent and least nucleophilic of the amide bases. It is kinetically faster than LDA, and will smoothly do many deprotonations not possible with LDA. Interference by the amine (e.g. in acylations) is minimal because of high steric hindrance. Disadvantage: the
