Chemical compound

Picryl chloride is an organic compound with the formula ClC₆H₂(NO₂)₃. It is a bright yellow solid that is highly explosive, as is typical for polynitro aromatics such as picric acid. Its detonation velocity is 7,200 m/s.

Reactions[edit]

The reactivity of picryl chloride is strongly influenced by the presence of three electron-withdrawing nitro groups. Consequently picryl chloride is an electrophile as illustrated by its reactivity toward sulfite to give the sulfonate:^[2]

ClC₆H₂(NO₂)₃ + Na₂SO₃ → NaO₃SC₆H₂(NO₂)₃ + NaCl

Picryl chloride is also a strong electron acceptor. It forms a 1:1 charge-transfer complex with hexamethylbenzene.^[3]
