Description

Application

2,3-Dibromo-N-methylmaleimide can be used to synthesize bis-indolylmaleimides via reaction with indolyl magnesium bromide. It can also undergo mono-cross coupling with triorganoindium derivatives which can be further coupled with naphthodithiophene to form an intermediate for [5]thiahelicene synthesis.
