Route of Synthesis (ROS) of Penrakis(di merhy lam i no)ranralum(V) CAS 19824-59-0
ConditionsYieldStage #1: tantalum pentachloride; dimethyl amine In n-heptane; water at -20℃; for 10h; Inert atmosphere;Stage #2: With n-butyllithium In n-heptane; water at -20℃; for 22h; Temperature; Solvent; Reflux;Experimental ProcedureUnder an argon atmosphere, 720 g of tantalum pentachloride and 2000 ml of water were charged into the reaction vesselN-heptane,Under stirring, 540 grams of anhydrous dimethylamine was added to the reaction kettle,The addition rate was maintained at -20 ° C,After the temperature was added to maintain the system for 10 hours,Then, n-butyllithium n-heptane (4400 ml, 2.5 mol / L)The temperature of the system was maintained at -20 ° C during the addition process, and the reaction was completed for 18 hours and then refluxed for 4 hours.Cooling first decompression to 1000Pa distilled solvent n-heptane, the temperature was 50 . After the solvent is evaporated to dryness, the solid is transferred to a sublimer,Finally, the pressure was again reduced to 50Pa sublimation products pentamethylamino) tantalum, the temperature is 50-100 , to give the productPenta (dimethylamino) tantalum698.4 g, yield 87.3%.87.3%
