By means of reactions involving transition metal chlorides MClx and lithium dialkylamides a number of new dialkylamino-derivatives of titanium, zirconium, vanadium, niobium, tantalum, chromium, molybdenum and tWlgsten have been prepared. Aminolysis of some of these compounds involved considerable steric effects due to shielding of the metal atom. In the case of quinquevalent niobium and tantalum the steric effect precluded the formation of pentakis-derivatives except with dimethylamino-, N-methyl--butylamino-,and piperidino-groups. With higher dialkylamines the products were NbNRzhl and RNTaNRz3. Studies on the reactions of dialkylamino-titanium compounds with primary amines showed that polymeric compounds may be obtained.
