Lithium t-butoxide synthesis

WebTorsional isomerism is very fast with allylmagnesium and -lithium compounds [Ea EJ 10 kcal/mol (ref. U)]. In contrast, it takes many hours for most allyl-type potassium compounds [Ea 2 20 kcal/mol] unless it is catalyzed with magnesium (ref. 14), lithium (ref. 14) or mercury (ref. 15) derivatives. The striking difference in rates is WebPotassium tert-butoxide (or potassium t-butoxide) is a chemical compound with the formula [(CH 3) 3 COK] n (abbr. KOtBu).
