Lithium triisobutylhydroborate

Features

Lithium tri-sec-butylborohydride is a new type of hydride reducing agent, which has the characteristics of strong reducing ability and high regio- and stereoselectivity.

Preparation

Lithium triisobutylhydroborate can be prepared by:In a 3000ml three-necked flask, add 1000ml of 1mol/L tri-sec-butylboron tetrahydrofuran solution, add 1000ml of 1mol/L triethylenediamine tetrahydrofuran solution simultaneously, introduce nitrogen to start stirring, put the mixture of the two in an ice-water bath After cooling to 0° C., 1000 ml of a 1 mol/L lithium aluminum hydride solution in tetrahydrofuran was slowly added dropwise to the above mixed solution with a constant pressure funnel for about 10 hours.

Physical properties
