Route of Synthesis (ROS)
| Conditions | Yield |
| With chloro-trimethyl-silane In tetrahydrofuran at 20℃; for 5h; Schlenk technique; Inert atmosphere; Experimental Procedure A Schlenk vessel was charged with tetrakis(dimethylamido)zirconium(IV) (135mg, 0.507mmol), dry THF (30mL) and a stirring bar. Under protection from air, 2 (200mg, 1.01mmol) was added. After the solution was stirred at room temperature for 2h, all volatile materials were removed on a vacuum line. To the solid residue, an excess of trimethylchlorosilane (5mL) was added to effect exchange of amido ligands versus chloro ligands. After the mixture was stirred at room temperature for 3h, volatile materials were removed on a vacuum line. The solid residue was triturated with dry n-hexane, filtered off, and dissolved in a small amount of dry dichloromethane. Crystallization afforded the product in the form of yellow needles. Yield: 200mg (71%). M.p. 255-259°C. 1H NMR (300MHz, CD2Cl2, 298K): δ=6.27 (s, 1H), 6.82 (d×d, J=6.30Hz, J=6.44Hz, 1H), 7.13 (d, J=8.03Hz, 1H), 7.50 (m, 3H), 7.59 (d×d, J=7.0Hz, 1H), 7.95 (d, J=5.71Hz, 2H), 8.48 (d, J=5.39Hz, 1H) ppm. 13C NMR (75MHz, CD2Cl2, 298K): δ=104.0, 120.4, 126.2, 126.4, 129.4, 130.6, 136.0, 139.9, 149.2, 155.4, 160.2ppm.
