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

    When you see the mechanism of claisen rearrangement. ie sigmatropic rearrangement you will find that group is reversed...this is supported by tracer studies by doing isotopic label...
