2,3-Dibromomaleinimide Chemical Properties,Usage,Production

Uses

2,3-Dibromomaleimide may be used in the synthesis of the following:

• 2-bromo-3-(1H-indol-3-yl)maleimide via reaction with indolyl magnesium bromide in tetrahydrofuran
• 2-dibromo-3-propylsulfanyl-maleimide via reaction with propanethiol and sodium acetate in methanol

General Description

2,3-Dibromomaleimide a cyclic imide, has a dipole moment of 0.30 debye based on ab initio and density functional theory (DFT) calculations.
