Potassium tri-sec-butylborohydride Structural

What is Potassium tri-sec-butylborohydride?

Description

Potassium tri-sec-butylborohydride [54575- 49-4] solution in tetrahydrofuran (THF) is sold as K-Selectride (Aldrich). These compounds may be used for highly stereoselective reductions, e.g., of ketones . Chemical rearrangements induced by potassium hydride are important in organic chemistry. Furthermore, in combination with other reagents potassium hydride acts as a catalyst in the polymerization of alkenes and dienes.
