One of the major reasons is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time, to discover the sequence of events that occur at the molecular level.4254-15-3, (S)-Propane-1,2-diol, introduce a new downstream synthesis route. 4254-15-3
Compound M31:; To a solution of (S)-1 ,2-propandiol (5 mmol) in 5 ml_ of anhydrous CH2CI2 were added 2-methyl-1-butene (5.5 mmol) and BF3 etherate (0.5 mmol) at room temperature. The stirring was continued for another 24 h. The solvent was removed by vacuum, and the residue was purified by chromatograph on silica gel to afford intermediate (4 mmol, 80 percent yield) as oil. Then, to a suspension of this intermediate and imidazole (6 mmol) in 6 ml_ of anhydrous THF was added 4.8 mL of TBDMSCI (1 M in THF) at 0 0C. The solvent was removed by vacuum, and the residue was re-dissolved in Et2O. The heterogeneous mixture was filtered over a pad of Celite. The filtrate was washed with 1N HCI, water and brine, dried over Na2SO4 and concentrated in vacuo. The residue was chromatographed to give pure M31 (0.34 mmol, 85percent yield) as oil.
This molecular description is the mechanism of the reaction; it describes how individual atoms, ions, or molecules interact to form particular products.If you are interested, you can also browse other articles of 4254-15-3, We look forward to the emergence of more reaction modes in the future.
