{ALF} Also used in the Wittig reaction, to give Li salt-free product distribution for selective (Z)-alkene formation: J. Org. Chem., 45, 4260 (1980). Has also been used with 18-crown-6 for selective formation of (Z)-ɑß-unsaturated esters from phosphonates: Tetrahedron Lett., 24, 4405 (1983).

{ALF} Sterically hindered strong base, compare Sodium bis(trimethylsilyl)amide, L13352 and Lithium bis(trimethylsilyl)amide, L15012. Used in the generation of K enolates, preferred to their Li or Na counterparts in some reactions, see e.g.: Tetrahedron Lett., 32, 1779 (1991); J. Am. Chem. Soc., 109, 6881 (1987); 111, 1063 (1989).
