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., 1122-10-7
General procedure: To a stirred solution of 2,3-dibromomaleimide23 (1.0 mmol) in CH2Cl2 (20ml) Et3N (2.0mmol) and thiol (2.1mmol) were added under argon atmosphere and stirred for 3 h at room temperature. The reaction mixture was evaporated,and the crude product was purified by flash chromatography to give the desired compound.
