Phosphorus pentachloride → HCID 12346245, compound

Participants

Reaction Steps

Stoichiometrically one mole of phosphorus pentachloride (PCl5) should be consumed for each mole of N,N'-bis(2,4,6-trinitrobenzoyl)hydrazine in the reaction to produce 2,5-dipicryl-1,3,4-oxadiazole. However, for better results a molar excess of PCl5 is used. A molar ratio of PCl5 to N,N'-bis(2,4,6-trinitrobenzoyl)hydrazine of from 1.0:1.0 to 3.0:1.0 is preferred, with from 2.0:1.0 to 2.5:1.0 being more preferred.
