Route of Synthesis (ROS)
Route of Synthesis (ROS) of Tetrakis(dimethylamino)tin(IV) CAS 1066-77-9
ConditionsYieldWith 2,2',2''-triaminotriethylamine In diethyl ether Glovebox; Inert atmosphere; Sealed tubeExperimental Proceduret-BuSn(NMe2)3 is prepared by the reaction of t-BuMgCl and Sn(NMe2)4 in diethyl ether; t-BuMgCl (2.0 M) and Sn(NMe2)4 (99.9% trace metals) are produced by Sigma-Aldrich (Sigma-Aldrich) provided. In this reaction, the tertiary butyl group from Grignard reagent replaced a dimethylamino group (-N(CH3)2). The 119 Sn NMR spectrum in Figure 3 shows that the approximate molecular purity of the product t-BuSn(NMe2)3 (δ= -85.6 ppm) is 94% by peak integration; 1% is (t-Bu)2 Sn (NMe2 )2 (δ= -56.2 ppm), and the remaining 5% is Sn(NMe2 )4 (δ= -120.2 ppm).In a glove box filled with Ar (g) and >0.5 ppm O2 (g), put 1202.57 grams of t-BuSn(NMe2)3 into a 2-neck, 2-liter round bottom flask with a 1.25-inch egg-shaped stir bar. 34.3 g (6 mole %) of tris(2-aminoethyl)amine (TREN, Alfa Aesar) was added to the flask and stirred to form a milky white suspension. One neck of the 2-liter flask is equipped with a Teflon valve, and the other neck is sealed with a 24/40 glass stopper. Remove the flask from the glove box and connect to Schlenk tubing. Use the following packed column distillation settings to perform purification:• Hei-Tec stirring plate with Pt/1000 RTD probe and temperature feedback control. • Silicone oil bath.• 300mm vacuum jacketed 24/40 Hempel distillation column (Sigma-Aldrich)• 0.24 inch 316 stainless steel saddle wire mesh column packing (Ace-Glass)•Vacuum jacketed 24/40 short-path distillation head with water-cooled condenser (Chemglass)• 1 liter Schlenk bomb flask as a collection bottleVacuum distillation is performed using an oil bath temperature of 115°C to 120°C and an absolute pressure of about 500 millitorr (mTorr), so that the distillate vapor temperature is in the range of 58°C to 62°C. The initial distillate was not discarded and 872.6 grams of purified t-BuSn(NMe2)3 was recovered, resulting in a 77.2% yield. At the end of the distillation, approximately 275 grams of material remained in the distillation flask and packed column. 77.2%In tetrahydrofuran Glovebox; Inert atmosphere;58 %
