Substituted allyl aryl ethers undergo a Claisen rearrangement similar to the reaction described in text Section 24.13 for allyl phenyl ether. 2-Butenyl phenyl ether rearranges on heating to give o-( 1-methyl-2-propenyl)phenol. 

Operation of the insertion-elimination mechanism has been demonstrated in the reaction of rhodium hydride complex, RhHL4 (L=PPh3), with two isomeric allyl phenyl carbonates [56]. Unbranched 2-butenyl phenyl carbonate was found to give branched allylic phenyl ether exclusively, whereas the decarboxylation of the branched l-methyl-2-propenyl phenyl carbonate afforded unbranched 2-butenyl phenyl ether. These results can be accounted for by assuming a precata-lytic and catalytic insertion-elimination process as shown in Scheme 7. 

To a suspension of 2.24 g (20 mmol) of potassium rerf-butoxide in 20 mL of terf-butyl methyl ether under argon is added 2.31 g (10 mmol) of (S)-2-(methoxymethyl)-1-[( )-3-phenyl-2-propenyl]pyrrolidine30, and then the mixture is cooled lo — 78 °C and 7.1 mL of 1.69 M fm-butyllithium in pentane is added dropwise with stirring. After 2 h, 12 mmol of the haloalkane are added and the mixture is stirred until the brown-red solution becomes yellow. Then 30 mL of diethyl ether and 20 mL of 2 N hydrochloric acid are added, the mixture stirred for 12 h at 25 °C, extracted with three 40-mL portions of CH2CI2, the organic layer is washed with two 10-mL portions of NaHCOj and two 10-mL portions of water, dried with Na2S04, concentrated in vacuo and distilled (Kugelrohr).
