| Cp2ZrCl2-i-BuMgBr Reagent System - the reduction of alkenes and alkynes and two dimerization of olefins
Plastic chromatography mass spectrometry and chromatography-based Hitachi i63. In addition, the product of using high pressure liquid chromatography separation. . 3 olefins reactor (three neck bottle) full Tuo for argon, and then adding Cp2ZiCI292mg (1mmo1) and THF10mL, stirring to dissolve. Add i-BuMgBr2.4-retool the THF solution (about 2mL), stirred 1h,mbt shoes on sale, the solution color to brown. I. i added a Octene 12g (10mmo1), stirring 20h. Reaction is completed, it acidic by adding diluted hydrochloric acid. And then extracted with ethyl ether,buy ghd hair, ethyl ether layer washed, dried with anhydrous sodium sulfate. Remove the solvent residue in vain before chromatographic separation, and then use the preparative chromatography separation, that was fourteen 7-8 carbon alkyl or two methyl. The formation resultant one-dodecane as internal standard, chromatographic quantification. Structures. HNMR, MS. Other olefins, methods of operation and the same. ? 4-ene reaction of Bu has been processed by a NBS Cp. ZrC1. (1mmo1) and i-BuMgBr (2.4mmo1) reagent consisting of their own system and 1-ene (10retoo1) I, 603 - 3 way by reaction at room temperature the reaction solution by adding N-bromosuccinimide (NBS) 534rag (3retoo1),Tory Burch Shoes, stirred 1h. Reaction is complete, the acidic by adding diluted hydrochloric acid, extracted with hexane, water, dried with anhydrous sodium sulfate, after Sin, and the remaining operation and 3 to the same. Other en razor also carried out the same way. 5Cp2ZrCI with the i-BuMgBrg. ~ Reaction Cp? ZrC1z (2mmo]) and i-BuMgBr (4.8,; omo1) in THF (2omL) in the reaction solution with oxygen blowing, so that the resulting isobutene into Br: CCI solution of a bromide. Australian of the completed, CCI. Washed with aqueous sodium sulfite solution to remove excess bromine. Concentrated distillation residue was separated by liquid chromatography pendulum, which was 2-methyl-I,ralph lauren outlet, 2 - b O butane. Products identified with the former. 6 = olefins, alkynes basic operation, product analysis with the identification and 3 to the Jiu.
