Abstract
The 2-arylbenzoxazoles 3af were produced in moderate to excellent yields merely by stirring a potassium cyanide (3 equiv)-containing methanol solution of the borobicyclic compounds 1af at room temperature. These compounds were fully characterized spectroscopically [IR, 1H, and 13C NMR and X-ray analysis (3a)] and by elemental analysis.
