개요Lithium triethylborohydride is the organoboron compound with the formula LiEt3BH. Commonly referred to as LiTEBH or Superhydride, it is a powerful reducing agent used in organometallic and organic chemistry. It is a colorless or white liquid but is typically marketed and used as a THF solution. The related reducing agent sodium triethylborohydride is commercially available as toluene solutions.LiBHEt3 is a stronger reducing agent than lithium borohydride and lithium aluminium hydride.

용도Powerful and selective reducing agent.As a reducing agentLithium triethylborohydride is used as a powerful reducing agent in organic synthesis for the conversion of carbonyl compounds to alcohols. It is also used in the preparation of alkynyl alcohols from the cleavage of cyclic keto-vinyl triflates. It is also used in the reduction of esters and lactones to alcohol and diol respectively. Further, it is used to prepare 1-methylcyclohexanol and 1,4-butanediol from 1,2-epoxybutane and gamma-butyrolactone respectively. It is also utilized for reductive cleavage of mesylates and tosylates in synthetic organic chemistry.

일반 설명Super-Hydride solution (Lithium triethylborohydride or LiTEBH) is widely used as a powerful and selective reducing agent that shows super hydride activity in organic synthesis.

제조 방법

LiBHEt3 is prepared by the reaction of lithium hydride (LiH) and triethylborane (Et3B) in tetrahydrofuran (THF):LiH + Et3B → LiEt3BHIts THF solutions are stable indefinitely in the absence of moisture and air.
