Lithium Chloride → Lithium tri-s-butylborohydride

Participants

Reaction Conditions

Reaction Steps

456.85 g of potassium tri-sec-butylborohydride (1.4 molar in THF) were added to a mixture of 29.7 g LiCl in 50 ml THF at 65° C. The reaction mixture was stirred for 2-4 hours at 65° C., cooled to room temperature and then filtered. The filter cake was then washed twice with 79.1 g THF. The filtrates were combined yielding lithium tri-sec-butyl borohydride in tetrahydrofuran as a clear, pale yellow liquid (99+% pure by atomic absorption).
