Procedure

Sodium bis(n-propyldimethylsilyl)amide was prepared as follows: Sodium amide (1.26 g, 0.0322 mol) was placed in dry benzene and bis(n-propyldimethylsilyl)amine (7.00 g, 0.0322 mol) was added. The mixture was stirred and refluxed for several hours. The benzene solution was filtered through celite and then the benzene was evaporated under vacuum, leaving 6.31 g (82%) of a yellow liquid product, sodium bis(n-propyldimethylsilyl)amide. Its viscosity was measured to be 7.1×104 centipoise at 40° C. It was distilled at a temperature of 213° C. and a pressure of 0.3 torr.
