Procedure

A solution of 4.87 g of neopentyllithium in pentane was added to a solution of 7.0 g of titanium tetrakis(dimethylamide) in pentane with stirring. Lithium dimethylamide precipitated rapidly. The total amount of pentane in the reaction mixture was about 50-100 ml. After being stirred for one hour the mixture was filtered, and pentane was evaporated from the filtrate to give 7.5 g (86%) of dineopentyltitanium bis(dimethylamide) as an air-sensitive yellow oil. Nmr C6D6 : δ (NMe) 3.23, δ (CMe3) 1.05 ppm downfield from tetramethylsilane.
