摘要

The rates of rearrangement of ten X-cinnamyl p-tolyl ethers were determined with the object of obtaining information to define the electronic character of the traiisition state of the Claisen rearrangement. The rates were best correlated by u+-constants and a p-value of-0.40. Since the rates of rearrangement of allyl PX-phenyl ethers are similarly correlated by negative p- and u+-constants, the transition state must involve a depletion of electrons in both the aryl ...
