541-59-3, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.541-59-3, name is Maleimide. An updated downstream synthesis route of 541-59-3 as follows.
To a solution of maleimide (6.35 g, 65.4 mmol, 1.0 eq. ) in EtOAc (120 mL) were added N-methyl morpholine (8.6 mL, 78.5 mmol, 1.2 eq. ) and methyl chloroformate (6.0 mL, 78.5 mmol, 1.2 eq. ) at 0 . The reaction was stirred at 0 for 30 min and r.t. 1 h. The solid was filtered off and filtrate concentrated. The residue was dissolved in CH2Cl2and filtered through a silica gel plug and eluated with CH2Cl2to remove the color. The appropriate fractions were concentrated and resulted solid was triturated with 10%EtOAc/PE to give a white solid (9.00 g, 89%yield) .
A chemical reaction often occurs in steps, although it may not always be obvious to an observer. Thank you very much for taking the time to read this article. If you are also interested in other aspects of Maleimide, you can also browse my other articles.
