Potassium tert-pentyloxide is a strong, hindered base used in combination with lithium diisopropyl amide to generate a superbase for the selective metallation of the aralkyl system at the 6-position of protected estradiols. It is used in organic synthesis, agrochemicals, pharmaceuticals, colorants and aroma chemicals. It acts as a catalyst in polymerization and isomerizations.
Strong, hindered base, soluble in hydrocarbon solvents: J. Am. Chem. Soc., 108, 1306 (1987). Has been used in combination with LDA to generate a superbase for the selective metallation of the aralkyl system at the 6-position of protected estradiols: Synthesis, 1493 (1995).
