Description
| - Cyclic beta-enaminones bearing secondary amino group react with4-substituted benzenediazonium tetraphenylborates in dichloromethane to form substituted bicyclic [1,3,2 lambda(4)] oxazaborines The oxazaborines rearrange, on heating to 200 degrees C in the absence of solvent or in DMF or DMSO, to isomeric 2H-[1,2,4,3 lambda(4)] triazaborines. Previously prepared [1,3,2 lambda(4)] oxazaborines derived from acyclic beta-enaminones bearing secondary amino group either did not undergo the rearrangement or with a lot of difficulties and with negligible yield. The fluorescence behaviour of the prepared triazaborines was observed. These compounds fluoresce in 2-methyltetrahydrofurane and in solid state under low temperatures.
