Nitrogen tribromide
Nitrogen tribromide is a chemical compound with the formula NBr3. It is extremely explosive in its pure form, even at −100 °C, and was not isolated until 1975. It is a deep-red and volatile solid.Preparation
NBr3 was first prepared by reaction of bistrimethlysilylbromamine with bromine monochloride at −87 °C according to the following equation:
where "Me" is a methyl group. It reacts instantly with ammonia in dichloromethane solution at −87 °C to yield NBrH2.
