Yield:-

Reaction Conditions:

with phosphonic Acid for 2 h;Cooling with ice;Inert atmosphere;

Steps:

4 trimethylamine borane complex preparation
Using the similar reaction apparatus of Figure 1,The reaction chamber is 1000mL glass three bottles,Three bottles placed in ice salt bath.4.5g NaBH4 after grinding into borane generator,5 ml H3PO3 solution was added to the constant pressure funnel.The reaction chamber used argon to replace the air.When reacting,First connected to trimethylamine inert gas flow,Then slowly add concentrated H3PO3 solution to the borane generator, after 2 hours reaction,After the reaction chamber white sediment settlement is completed, close the settlement pipe and trimethylamine inlet valve,The white pure trimethylamine borane complex was collected.
