1122-10-7, The molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. If there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular.1122-10-7, name is 3,4-Dibromo-1H-pyrrole-2,5-dione. A new synthetic method of this compound is introduced below.
General procedure: Dibromomaleimide 1a, 2.0 g (7.84 mmol), was dissolved in 15 mL of anhydrous DMF, and 0.9 mL (9.51 mmol) of 4-fluoroaniline and 2 mL (11.5 mmol) of DIPEA were added. The mixture was stirred for 24 h at 50C and poured into a mixture of water and ethyl acetate. The organic layer was separated, washed with dilute aqueous HCl, and evaporated under reduced pressure, and the residue was purified by column chromatography using petroleum ether-ethyl acetate (5 : 1) as eluent.
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 3,4-Dibromo-1H-pyrrole-2,5-dione. We look forward to the emergence of more reaction modes in the future.
