A similar reaction combines these compounds with phosphines to yield primary amines, known as the Staudinger reaction. Acyl versions of these compounds can undergo the Curtius rearrangement to form isocyanates.  Inorganic salts of these compounds are often used in airbags due to the fact that they readily decompose into nitrogen gas.  For 10 points,, name these compounds that contain three nitrogens bound to each other.
