The thermal reaction of (Z)-2,3-diphenyl-2-(2,3-diphenyl-3-oxo-1-propenyl)-2H-azirine with or was reinvestigated to afford 2,3,5,6-tetraphenylpyridine along with the pyrroles and 1,3-oxazepine derivative.The formation of 1,3-oxa
BORON TRIFLUORIDE ETHERATE-CATALYZED REARRANGEMENT OF 2,4,6,7-TETRAPHENYL-1,3-OXAZEPINE TO GIVE NOVEL PYRIDONE RING SYSTEM

The boron trifluoride etherate causes an efficient rearrangement of 2,4,6,7-tetraphenyl-1,3-oxazepine to lead to 2,2,4,6-tetraphenyl-3-pyridone and 3,3,4,6-tetraphenyl-2-pyridone.The BF3-coordinated pyridine-2,3-oxide is proposed as a reasonable intermediate.
