The Uses of (Dimethylsilylene)bis(2-methyl-4-phenylindenyl)zirconium dichloride
Dimethylsilylene)bis(2-methyl-4-phenylindenyl)zirconium dichloride can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process.
Synthesis
To a solution of (2-methyl-4-phenylindenyl) silane ether / hexane = 1/1 (12.4 mmol) in 240 mL of n-butyllithium(2.5 M in hexane) was slowly added dropwise at -78 ° C. After that, the mixture was stirred at room temperature for one day, filtered and vacuum dried to obtain a pale yellow solid. A ligand salt synthesized in a glove box and bis (N, N'-diphenyl-1,3-propanediamido)Dichloro zirconium bis (tetrahydrofuran) was weighed in a Schlenk flask, ether was slowly added dropwise at -78 ° C, and the mixture was stirred at room temperature for one day.The red solution was separated by filtration, dried in vacuo, and a toluene / ether = 1/2 solution was added to obtain a clear red solution. 1.5-2 equivalents of HCl ether solution (1M) was slowly added dropwise at -78 ° C, followed by stirring at room temperature for 3 hours. After filtration and vacuum drying, (Dimethylsilylene)bis(2-methyl-4-phenylindenyl)zirconium dichloride was obtained in a yield of 70% (racemic only).
storage
Pay attention to sealed storage, and the storage place should be cool and dry. Keep away from water.
