Lithium tetramethylpiperidide

|Section2=
}}
Lithium tetramethylpiperidide (often abbreviated LiTMP or LTMP) is an chemical compound with the molecular formula C9H18LiN. It is used as a non-nucleophilic base, being comparable to LiHMDS in terms of pKa and steric hindrance.
==Synthesis==
It is synthesised by the deprotonation of 2,2,6,6-tetramethylpiperidine with ''n''-butyllithium at -78 °C. Recent reports show that this reaction can also be performed 0 °C.〔(amide primer ) H. J. Reich 2002〕 The compound is stable in a THF/ethylbenzene solvent mixture and commercially available as such.
