WebLithium Diethylamide (LiNEt2). Used for isomerization of epoxides to allyl alcohols. Can be used for deprotonations of C-H acids, but is more prone to give addition products than more hindered amides like LDA. May be superior to LDA in sterically hindered situations. Lithium 2,2,6,6-Tetramethylpiperidide (LiTMP, pKa. 37). WebThe pK(Li) of these two amines fit well the previously found correlation with Hartree-Fock calculations at 6-31+g(d) using RLi coordinated with three dimethyl ethers as a computational model for RLi in THF. The results are also compared with earlier pK(Li)s reported from equilibria with lithium amides in which aggregation was not considered.
