The discovery-oriented approach to organic chemistry. 7. Rearrangement of trans-stilbene oxide with bismuth trifluoromethanesulfonate and other metal triflates: A microscale green organic chemistry laboratory experiment

A microscale discovery-oriented experiment illustrating the rearrangement of trans-stilbene oxide using non-corrosive metal triflates as catalysts has been developed. The use of CDCl₃ as the reaction solvent eliminates the need for any workup and avoids the use of highly toxic boron trifluoride etherate as a catalyst and additional reaction solvent.
