Applications

Lithium 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.

Notes

Moisture sensitive. Air sensitive. Incompatible with water and strong oxidizing agents.
