Carbonyl diazide

Carbonyl diazide is a chemical compound with the chemical formula CO(N3)2. In terms of its structure, it can be described as two azide groups \sN3 covalently attached to the carbonyl group \sC(\dO)\s by single bonds. It can be prepared by way of the reaction between triphosgene and tetra-n-butylammonium azide, in a dimethyl or diethyl solution.

The first synthesis of carbonyl diazide was reported in 1894, although there have been multiple alternative syntheses since then.
