- The existence of the NIH shift was established by determining the major product obtained from rearrangement of the following arene oxide, in which a hydrogen has been replaced by a deuterium. a. What would be the major product if the NIH shift occurs? (Hint: A C¬H bond is easier to break than a C¬D bond.)b.
