Abstract

AbstractThe reaction of methylmagnesium iodide with allyl phenyl ether was investigated. Contrary to expectation2 1‐butene, the product of the ether cleavage reaction, was formed only to a small extent, the main gaseous product being methane. The mechanism proposed for the formation of this product is: Claisen rearrangement of allyl phenyl ether under the influence of magnesium iodide and reaction of methylmagnesium iodide with the rearrangement product, o‐allylphenol with formation of methane. The formation of methane as well as of 1‐butene indicates that two competitive reactions (rearrangement and ether cleavage reaction) take place.
