Abstract
The reaction of N-methylpyrrolidin-2-one hydrotribromide complex (MPHT) with 2-methylbut-2-ene has been investigated. This compound proved to be a successful substitute of the dangerous molecular bromine used for bromination of olefins. It is a stable complex, not corrosive, not necrosing, nor moisture sensitive. Moreover, it has been shown that it is far less toxic than bromine, and therefore much easier for students to handle.
Supplement
Instructions for the students and notes for the instructor are available.
