K-selectride is the organoboron compound with the formula KBH(C₄H₉)₃. It is the potassium salt of tri(sec-butyl)borohydride. The compound is sold as solution in THF. It is a strong reducing agent. Solutions are pyrophoric and highly reactive toward water and protic compounds. It is handled using air-free technique. It is produced by the reaction of tri(sec-butyl)borane with potassium hydride. The reagent is used to reduce ketones to alcohols.^[1]
