To a stirred solution of 0.80 g of vanadium tetrakis(dimethylamide) in pentane was added a solution of 0.63 g of trimethylsilylmethyllithium in pentane. Lithium dimethylamide precipitated rapidly. The reaction mixture contained a total of about 50-100 ml of pentane. After stirring for three hours the mixture was filtered, and part of the pentane was evaporated. The solution was kept at -40° C. overnight, following which the remainder of the pentane was evaporated, to give bis(trimethylsilylmethyl)vanadium bis(dimethylamide) as a dark-green oil, which was purified by distillation at 100° C. under high vacuum.
