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.[2] It is a deep-red and volatile solid.

Preparation

NBr3 was first prepared by reaction of bistrimethlysilylbromamine (bis(trimethylsilyl)amine bromide) with bromine monochloride (with trimethylsilyl chloride as byproduct) at -87 °C according to the following equation:

(Me3Si)2NBr + 2 BrCl -> NBr3 + 2

where "Me" is a methyl group. It reacts instantly with ammonia in dichloromethane solution at -87 °C to yield NBrH2.
