**K-selectride** is the [organoboron compound](/source/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](/source/Air-free_technique). It is produced by the reaction of tri(sec-butyl)borane with [potassium hydride](/source/Potassium_hydride). The reagent is used to reduce [ketones](/source/Ketone) to alcohols.[1]
