Allyl ethers of orf/io-disubstituted phenols rearrange to the corresponding p-allylphenols. It is noteworthy that the para rearrangement is not usually accompanied by inversion of the allyl group.8-4-6-6-7 For example, cinnamyl 2-carbomethoxy-6-methylphenyl ether (III) rearranges without inversion8 to yield the p-cinnamyl derivative (IV). 

The-Claisen rearrangement to the ortho position is a first-order reaction,67 68 and the process does not require catalysis by acids and bases. The rearrangement is intramolecular, since rearrangement of mixtures of ethers such as allyl /3-naphthyl ether and cinnamyl phenyl ether,60 or cinnamyl 4-methylphenyl ether and allyl 4-aminophenyl ether,68 yields none of the cross products which would result from an intermolecular reaction. The process is best represented by the cyclic mechanism, in which the following processes take place, with the electronic shifts during reaction indicated by the arrows.23 39 69... 

Allylphenols and derivatives with substituents in the allyl group can, be prepared by direct C-alkylation of the sodium salt of the phenol in benzene solution.16 This method is not as good for the preparation of allylphenols themselves as the one involving preparation of the allyl ether followed by rearrangement, because a mixture of several products is obtained in C-alkylation. Thus the alkylation of p-cresol in benzene with sodium and allyl bromide yields 20% of allyl 4-methylphenyl ether, 8% of allyl 2-allyl-4-methylphenyl ether, 40% of 2-allyl-4-methyl-phenol, and 15% of 2,6-diallyl-4-methylphenol.16 The rearrangement of allyl 4-methylphenyl ether, however, yields 2-allyl-4-methylphenol in practically quantitative yield, and the ether is easily obtained.

The crotyl ether of the same phenol also rearranges without inversion. The only known example of para rearrangement accompanied by inversion is the reaction of a-ethylallyl 2-carbomethoxy- methylphenyl ether (V), which yields the p-(7-ethylallyl) derivative (VI). ...
