        • {ALF} Strong base of relatively low nucleophilicity. Review: Chem. Rev., 74, 45 (1974). The nucleophilicity is increased in the presence of 18-crown-6; the basic strength less so: J. Org. Chem., 43, 447 (1978).

        • {ALF} Combinations of KO-t-Bu with other strong bases are used to generate "superbasic" media, e.g. with n-BuLi: J. Organomet. Chem., 8, 9 (1967); Pure Appl. Chem., 60, 1627 (1988); Tetrahedron Lett., 29, 4991 (1988); see also Phenyl­acetyl­ene, A12139, 2-Methyl­indole, A10764, etc. In combination with Li 3-aminopropanamide, promotes the "zip" reaction for isomerizing alkynes to the terminal position; see 1,3-Diaminopropane, A11932, and Org. Synth. Coll., 8, 146 (1993). For use in combination with LDA for isomerization of epoxides to allylic alcohols, see Cyclohexene oxide, A13185.
        • {ALF} Treatment of a methyl ester in ether with the reagent provides a simple method for preparation of tert-butyl esters: Synlett, 658 (2001).
        • {ALF} For generation of dibromocarbene, see Bromoform, A11904. In combination with a solid-liquid phase-transfer catalyst in the absence of solvent, has been recommended for the dehydrobromination of alkyl bromides to alkenes: J. Org. Chem., 49, 1138 (1984): with 18-crown-6, is effective for the dehydrobromination of vic-dibromides: Liebigs Ann. Chem
