WebPotassium tert-butoxide (or potassium t-butoxide) is a chemical compound with the formula [ (CH 3) 3 COK] n (abbr. KOtBu). This colourless solid is a strong base (pKa of conjugate acid around 17), which is useful in organic synthesis. The compound is often depicted as a salt, and it often behaves as such, but its ionization depends on the solvent. Web(CH3)3COK, 2. H3O+ These reagents can carry out the required synthesis. Step-by-step explanation First component is a base which results in the formation of alkene by dehydrohalogenation of the substrate. Then, second component will hydrolyze (i.e. add H 2 O) the alkene into secondary alcohol according to Markovnikov rule of addition.
