The rearrangement of 4-arylazo-2-oxazolin-5-ones (1) with active methylene compounds was investigated. The 1,2,4-triazolyl derivatives (11) could be obtained on treatment of with 2-pyrazolin-5-one derivatives. The behaviour of the synthesised derivatives toward an aromatic diazonium salt was also investigated.
