rom the above mechanism, it is evident that during this rearrangement, it isthey-carbon of the allyl group (w.rL the oxygen atom) which gets attached to the ring carbon. In other words, during o-rearrangement Dnang 16 reversed. This is supported by tracer studies. Thus, when allyl phenyl ether having "C tracer at the y-position was subjected to Claisen rearrangement, the rearranged product had the "Ctracer attached to the ring D -CH2 CH= CH2 OH B CH CH=CH2 475 K Iyc1-Allyl phenyl ether [oC-o-Allylphenol Similarly when crotyl phenyl ether was subiected toCl the methvl ara
